Pressure Drop Characteristics Across Different Industrial Valve Types

Pressure Drop Characteristics Across Different Industrial Valve Types

Pressure drop significantly affects the design and operation of industrial valve systems. It refers to the reduction in pressure as fluid flows through a valve. Several factors influence this phenomenon, including valve type, flow rate, fluid properties, and valve geometry. Understanding pressure drop ensures efficient and safe operation of fluid systems. Here’s a detailed description of the pressure drop as it applies to various types of industrial valves:

Ball Valves


Ball valves offer simplicity, durability, and tight seals in industrial applications. The valve uses a spherical ball with a hole through the middle, aligning with the pipeline to allow or block flow.

Pressure Drop Characteristics:
  • Low Pressure Drop: Fully open ball valves exhibit a low pressure drop due to their straight and unobstructed flow path. The smooth, rounded interior of the ball minimizes turbulence and resistance.
  • Impact of Partial Opening: Partially open ball valves significantly increase pressure drop. The fluid navigates around the partially obstructed path, creating turbulence and resistance.
  • Valve Size and Flow Rate: Larger ball valves and higher flow rates reduce the relative pressure drop, but designers must consider potential cavitation and erosion.

Gate Valves


Gate valves primarily control on/off flow in a pipeline. They consist of a gate (or wedge) that moves up and down to start or stop the flow.

Pressure Drop Characteristics:
  • Minimal Pressure Drop when Fully Open: Fully open gate valves exhibit very low pressure drops because the gate remains entirely out of the flow path, allowing fluid to pass with minimal resistance.
  • High Pressure Drop during Partial Operation: Partially open gate valves significantly increase turbulence and pressure drop, making them unsuitable for throttling applications.
  • Design and Maintenance: When open, a straight-through flow path minimizes pressure drop, but over time, wear and tear on the gate and seat can impact performance and increase pressure drop.

Globe Valves


Globe valves excel at regulating flow and are used in applications requiring precise flow control. They consist of a movable disk-type element and a stationary ring seat in a spherical body.

Pressure Drop Characteristics:
  • Higher Pressure Drop: Globe valves inherently exhibit higher pressure drops than ball and gate valves due to the fluid changing direction as it passes through the valve. The tortuous path creates more resistance.
  • Flow Control: Globe valve design makes them ideal for throttling and precise flow control, but this advantage comes with higher pressure drops.
  • Valve Position: The valve opening degree significantly affects the pressure drop. Partial opening creates more resistance and higher pressure drops due to increased turbulence.

Butterfly Valves


Butterfly valves control flow using a rotating disc. They are commonly used in applications requiring quick shut-off and suit large-diameter pipes.

Pressure Drop Characteristics:
  • Moderate Pressure Drop: Fully open butterfly valves exhibit moderate pressure drops because the disc remains in the flow path even when rotated to the open position, creating some obstruction and turbulence.
  • Variable Pressure Drop: The pressure drop increases as the valve moves towards the closed position. The partially obstructed disc increases flow resistance and turbulence.
  • Efficiency and Application: Butterfly valves efficiently handle large volumes of flow with moderate pressure drops. They are often used in water distribution, HVAC systems, and various industrial applications where space and weight considerations matter.

Factors Influencing Pressure Drop Across Valves


Several factors influence pressure drop across industrial valves:
    1. Valve Design: Internal valve geometry, including the flow path and obstructions, plays a significant role.
    2. Flow Rate: Higher flow rates generally increase pressure drop due to greater frictional forces.
    3. Fluid Properties: Fluid viscosity and density affect how they interact with valve surfaces.
    4. Valve Size: Larger valves typically exhibit lower pressure drops for a given flow rate than smaller valves.
    5. Operational Conditions: Valve position (fully open, partially open, or closed) significantly affects pressure drop.

Understanding these characteristics helps select the appropriate valve for specific applications, ensuring efficient and safe operation while maintaining desired flow control and minimizing energy losses.

Plugged Chute Detection Technology: The Superiority of RF Admittance

The Best Plugged Chute Detection Technology: The Superiority of RF Admittance

The operation of industrial processes is a delicate balance of efficiency, safety, and maintenance. A crucial part of maintaining this balance is ensuring the smooth operation of material handling systems, which often employ chutes to transport bulk materials. One common complication these systems face is the problem of chute blockages or plugging, a critical issue that can lead to costly downtime, equipment damage, and potential safety hazards.


Plugged chute detection technologies mitigate these challenges, offering early detection and warning of chute blockages. However, the effectiveness of these technologies varies, and understanding their characteristics is essential for making an informed decision.


Overview of Plugged Chute Detection Technologies

Plugged chute detection technologies fall into three broadly classified groups, mechanical, acoustic, and electromagnetic methods.


Mechanical systems, such as tilt switches and paddle wheel indicators, are simple and inexpensive but prone to mechanical failure and false alarms due to vibration or material buildup. They also require regular maintenance to function effectively.


Acoustic detectors, on the other hand, utilize microphones to listen for changes in the acoustic signature of material flow. While this can be an effective method, it is sensitive to environmental noise and requires sophisticated signal processing to distinguish between normal and blocked flow.


Electromagnetic methods include capacitive probes, microwave radar, and RF Admittance. These offer non-contact detection and are less prone to false alarms and mechanical failures—however, the material's properties, environmental conditions, and installation setup affect their performance and application.


RF Admittance: The Optimal Choice

After an extensive review of these technologies, RF Admittance emerges as the overall best selection for plugged chute detection for several reasons:


Reliability

RF Admittance technology uses a probe to measure changes in the dielectric constant (a property of materials that affects their response to an electric field) between the sensor and the chute wall. When the chute is clear, the admittance (the measure of how easily a circuit or device allows an electric current to pass) between the probe and chute wall will be at one level, and when the chute is blocked, the admittance will change significantly. This reliable detection method leads to fewer false alarms than mechanical and acoustic systems.


Resistance to Material Buildup

One of the significant advantages of RF Admittance technology is its resistance to material buildup on the probe. The technology uses a driven shield construction that ensures only the material near the active sensor affects the reading. This feature helps to eliminate the risk of false alarms due to material buildup, a common issue in other technologies.


Versatility

RF Admittance technology works with various materials, regardless of their conductive or non-conductive properties, making it a versatile solution in different industries handling multiple types of bulk materials.


The Drexelbrook Solution


The Drexelbrook Plugged Chute Detector consistently identifies whether material is flowing through chutes. If the material ceases to flow due to a blockage, an alarm from the flush-mounted capacitance sensing element will be triggered, prompting further necessary actions such as notifying an operator or shutting down a conveyor belt.


The Drexelbrook detector, also known as a blocked chute switch, reliably tracks the presence or absence of bulk solids material in chutes without compromising flow speed. This cost-effective device ensures the continuous flow of materials.


Its robust sensor design makes this point-level switch optimal for handling materials such as coal, wood chips, ores, and powders. Since it is flush mounted through a chute wall, there is no protrusion into the chute to hinder or obstruct material flow.


The point-level switch can automatically identify and disregard coatings, thus preventing false alarms. It features a universal power supply that auto-detects and adjusts to the input power source.


Unlike similar technologies, the point-level switch for detecting plugged chutes permits remote electronics installation at a convenient or safer location.


The dependable detection of plugged chutes ensures smooth plant operations and significantly reduces the chance of spills due to blockages.


Key Features:

  • Availability of both curved and flat sensors
  • DPDT relay dry contacts rated at 5A, 120VAC
  • Requires less maintenance compared to other technologies; devoid of any moving parts that could potentially hang up or wear out
  • Utilizes Drexelbrook PML series electronics
  • Auto-detecting supply voltage range: 19-250 VAC, 18-200 VDC, without the need for jumpers

Trunnion Mount Valves

Trunnion Mount Valves

Trunnion mount valves are a type of industrial valve used to control the flow of fluids, such as liquids, gases, and slurries, in high-pressure systems. The term "trunnion mount" refers to how the valve mounts on a trunnion, a cylindrical projection that serves as a pivot point for the valve.

The valve body is typically made of metal, such as cast iron, steel, or stainless steel, and may be lined with materials such as PTFE or rubber to improve corrosion resistance and reduce wear. The valve stem, the part of the valve that rotates to open and close the valve, is also usually made of high-strength metal.

One of the most common uses of trunnion mount valves is in oil and gas production and transportation. These valves are often used in pipelines to control the flow of crude oil, natural gas, and other hydrocarbons. They are also commonly used in chemical plants, power plants, and other industrial facilities to control the flow of fluids in high-pressure systems.

Due to the need for tight shutoff and precise flow control, trunnion mount valves are typically used in high-pressure systems operating at 600 psi or higher pressures. They are also designed to handle high-pressure differential applications and are operated manually, pneumatically, or electrically.

SIL Level Switch Is Specifically Designed for Floating Roof Tanks

Capacitance Probe Level Switch Is Specifically Designed for Floating Roof Tanks

One of the most difficult and critical applications is measuring the high alarm or potential overfill condition on a floating roof tank containing liquid petroleum products such as crude oil or refined products such as fuel. It normally is comprised of a cylindrical steel tank equipped with an internal or external floating roof, that floats on the surface of the stored liquid. Floating roof tank systems are especially beneficial in eliminating the evaporative losses of the liquids. As opposed to a fixed roof tank there is no vapor space in the tank. This helps to reduce risk in highly explosive vapor environments. This is an extremely high cost of failure application, and one in which only the safest and most trusted products are accepted.

Safe operation of the tank farm relies on critical real time continuous level measurements of the liquids in the tank, as well as detecting when a high level condition exists. Products used in this application are typically required to meet the API 2350 Overfill Protection Standards, as well as SIL Safety Integrity Level performance standards to IEC 61508.

The challenges to reliably detect a high level condition on a floating roof tank are long sensor length requirements, and the variability of what is being measured. The floating roof may be dry in which case you need to detect the position of the physical metal roof. Or there may be a few inches of rain water or petroleum liquids on the roof. Measuring instruments need to determine very accurately, usually within a few millimeters, when the position of the floating roof has reached

The Drexelbrook SIL IntelliPoint capacitance probe level switch is specifically designed for Floating Roof Tanks (internal and external roofs) with a flexible brass level sensing probe. The level probe sensing element is field adjustable for lengths up to 15' (4.6 m). Electronics are designed to meet API 2350 Overfill Protection.

This level measurement system is specifically designed for spill prevention in floating roof tanks (internal and external roofs) using the IntelliPoint level switch with a flexible level sensing element for ease of installation (model 700-0005-595).

This level measurement system meets API 2350 regulations. It is ideal for use in safety related systems with requirements for functional safety for SIL2 in accordance to IEC61508-2, ed2, 2010 (Exida).

To prevent false alarms this level measurement system automatically recognizes and ignores coatings and is supplied with continuous self-test monitors circuits and sensing elements to detect faults.

A dual compartment housing separates the customer wiring from the sensing element and operating circuits. The encapsulated power supply/terminal block design eliminates the possibility of damage caused by moisture in the conduit.

The Floating Roof Tanks system comes with field adjustable lengths from 1' to 15' (0.3 to 4.6 m).

The system is based on our Manual Certify principle which allows the entire system to be manually tested without removing the sensor from the tank. The Manual Certify test checks that the Auto Verify circuits are operating and confirms the probe and cables are properly connected. Furthermore, the Manual Certify feature allows the electronics to sense changes in the probe that simulate contact with the media or floating roof. This provides the user with a method to ensure working performance without having to climb the tank.

No calibration or setpoint adjustments are required.

Key Features
  • Loop or Line Powered
  • Wetted Parts: 316SS 3/4" NPT Mounting, 3/16" FEP insulated flexible and adjustable cable, non-sparking brass sensor.
  • Automatic and local or remote manual test functions ensure proper system operation.
