Advanced Valve Assemblies for Liquid and Gas Venting and Safety Shut-Off Operations

FM classes 7400, 7412, 7420, and 7422 are standards and certifications established by FM Global, a large insurance company emphasizing loss prevention services. Each class specifies particular requirements for equipment and systems used in industrial and commercial settings. These classifications are part of FM Global's comprehensive approach to ensuring safety and reliability in equipment and systems related to fire protection and risk reduction.

A-T Controls manufactures FM-approved valve assemblies for liquid and gas vents and safety shut-off requirements. These valve assemblies have received FM approval, certifying their suitability for applications that demand protective measures for fuel-burning equipment by FM classes 7400, 7412, 7420, and 7422. Each assembly comprises a spring return automated ball valve, an explosion-proof limit switch, and a solenoid pilot valve. Customers can choose from two designs for the valves: a 3-piece design, which offers options for threaded, socket weld, or butt weld end connections, and a flanged design, available in ASME Class 150 and 300. These valves come in sizes from 1/4 inch to 6 inches. The assemblies are at the forefront of quarter-turn automation technology, featuring a rack and pinion actuator. In synergy with the assembly's superior valve seating and stem seal design, this actuator ensures reliable and consistent closure and venting as required. These assemblies offer a compact, efficient solution for fuel gas safety shut-off or venting systems.

Protective Coating Options for the Series 3R Rack and Pinion Actuators

The standard coating option for the Series 3R rack and pinion actuator is a hard anodized coating. The body is coated inside and out with epoxy-coated end caps. The carbon steel pinions are zinc plated, and all the fasteners are stainless steel. This standard coating is suitable for most general and industrial applications.

Electroless nickel plating is another actuator coating option. This coating applies externally and internally. Electroless nickel coating provides excellent corrosion resistance for acid mines or caustic wash downs with sodium or potassium hydroxide.

Another coating option is PTFE infusion, which is also applied internally. This coating is excellent in seawater applications as it can withstand an ASTM B117 salt fog spray test. PTFE infusion is also ideal for caustic washdowns with sodium or potassium hydroxide.

A marine epoxy coating option for the actuator body may also be added to other items, such as valves and gearboxes. This coating is an excellent preventer of corrosion in marine service environments and is available in custom paint colors to meet your specifications.

Another option is not a coating, but instead, the series S2 all stainless steel rack and pinion actuator. This actuator has an electro-polished finish and is an excellent economical solution to harsh chemical environments. It is ideal for the chemical-resistant requirements of the pharmaceutical, food and beverage, pulp and paper, and petrochemical industries. Series S2 actuators can be coupled directly to stainless steel valves and accessories to create a complete stainless steel automated package.

All Stainless Steel Ball Valve and Actuator Systems

Ball valves control flow by rotating a spherical ball within the valve, which contains an opening or port, through which liquid can flow when turned to align with the flow direction. When the ball rotates 90 degrees, the port becomes perpendicular to the flow direction, preventing fluid from passing through the valve. Stainless steel construction is advantageous in a flow control ball valve because it is highly corrosion and contaminant resistant, requiring less cleaning and maintenance and often providing a longer service life. 

Stainless steel pneumatic actuators are available in spring return, double acting, fail open, and fail close configurations. A corrosion resistance surface - resistance to most corrosive materials - is one of the advantages of using a stainless steel actuator. The stainless steel pneumatic actuator is excellent for heavy-duty automation, especially in corrosive environments. Stainless steel actuators with a durable stainless steel body manufactured to NAMUR standards continue to perform in the harshest environments. 

Piping Specialties' stainless steel actuated ball valves provide exceptional accuracy and dependability in flow control and open/close operations, critical in manufacturing, chemical, oil & gas, wastewater, processing, and other applications. 

Piping Specialties is committed to providing the most suitable valve for your application. For more information about stainless steel valves, call 800-223-1468 or visit https://psi-team.com.

The COMPACT Quarter-turn Rack and Pinion Pneumatic Actuator

The Habonim COMPACT actuator is a quarter-turn rack and pinion pneumatic actuator that doubles the torque of conventional pneumatic actuators. Habonim's patented four piston design, which generates torque around a centrally located piston, is responsible for superior performance, translating to double the power for the same size actuator or half the size for the same power. 

The COMPACT has four small cylinders, one on each of the cube's four sides. The smaller pinion and minimized travel distance of the pistons in the COMPACT require less air pressure to produce the same torque output as a larger double piston actuator. As a result, there's a reduction in emergency shutdown response, air consumption during operation, and maintenance.  Habonim's unique quarter-turn COMPACT actuators have the superior performance of twice the torque per size, much longer cycling before any care, high opening and closing speed, and exceptional durability in the most demanding industrial environments. 

STANDARD ACTUATOR FEATURES

NAMUR & ISO interface

A wide range of accessories such as solenoids, positioners, and limit switches are available for direct mounting to the COMPACT actuator, and any accessory with ISO 5211 and VDI/VDE 3845 (NAMUR) will mount to the actuator. 

NAMUR VDI/VDE 3845

This standard specifies various accessories with VDI/VDE interfaces, such as limit switches, pucks, indicators, and positioners, with simple mounting onto the actuator top face. 

NAMUR solenoid mounting

One of the four actuator covers available includes a pad for solenoid mounting per the NAMUR international standard. Any solenoid that conforms to the NAMUR interface can be directly mounted to the actuators, simplifying solenoid installation and eliminating the need for additional piping. Because the pressurized air supply is available at the port entrance, it also allows for quick actuation response. 

ISO 5211

The actuator bottom flange conforms to the ISO 5211 international standard and includes a star-shaped female drive to accommodate a wide range of valve output shafts. The valve can be attached to the actuator with a bracket or mounted directly onto the actuator using one of the ISO hole patterns.

COMPACT actuators are part of control packages in various industries and providing superior performance in the cycle times, size, weight, compressed-air consumption, and reliability in high cyclic applications.
