ARCA Control Valves in New England


ARCA develops, manufactures, and markets control valves on an international scale primarily for the chemical, food, power, and oil and natural gas industries.

High-performance control valves from ARCA are capable companions in industrial and large-scale power plants by ensuring safe and reliable operation and can be used in all high and low-pressure steam, oil, gas, water/boiler feedwater, and condensate circuits.

Oil and natural gas are the primary sources of energy driving the global economy. ARCA valves have helped ensure production and process reliability in the oil and natural gas industries for many years, and a wide variety of precision-engineered control valves are available that include DN15 (1/2) to DN600 (24") and PN16 to PN400 (ANSI 150-2500) sizes as well as special-purpose valves for all media handled in these areas.

ARCA valves are also indispensable in steel production. Steel production and processing require valves that offer ultra-high performance and a long service life.

Integrated in the bypass section of turbo-compressors, ARCA valves reliably carry out multiple tasks simultaneously by assisting during the start-up and shut-down phases of the compressor.

Concentrated Solar Power plants convert solar radiation into electrical energy. Systems that use  thermal oils as a heat-transfer medium produce temperatures that can reach 400 °C at approximately 40 bar in the solar array. Such applications integrate reliable ECOTROL® 6H high-pressure valves, which feature a bellows seal.

The BIOVENT® control valve developed for the food and pharmaceutical industry, for example, is available in many designs and connection layouts and with drives and positioners in stainless steel to cater to all applications.

FMCW (Frequency Modulated Continuous Wave) Open Air Radar Level Measurement

Non-contact level measurement using radar transmitters for the continuous, contactless level measurement of liquids, pastes, granulates, powders and other solids in a wide variety of industries.


Frequency Modulated Continuous Wave

OPERATING PRINCIPLE
  • The radar principle used is FMCW (Frequency Modulated Continuous Wave). The FMCW radar emits a high frequency signal whose frequency increases linearly during the measurement phase (called the frequency sweep). 
  • The signal is emitted via an antenna, reflected off the product surface and received with a time delay, t. 
  • Time delay, t=2d/c, where d is the distance to the product surface and c is the speed of light in the gas above the product. 
  • For further signal processing the difference Δf is calculated from the actual transmitted frequency and the received frequency. 
  • The difference is directly proportional to the distance.
  • A large frequency difference corresponds to a large distance and vice versa. 
  • The frequency difference f is transformed via a Fast Fourier Transformation (FFT) into a frequency spectrum and then the distance is calculated from the spectrum.
  • The level results from the difference between the tank height and the measured distance.

Custom 24" Pressure Balance Universal Elbow Expansion Joint by Hyspan

Pressure Balance Universal Elbow Expansion Joint

Elbow pressure balanced expansion joints (also known as corner relief expansion joints) are used on piping system where direction changes and the force exerted on piping and /or associated equipment from pressure thrust is intolerable. This arrangement uses dual connected bellows at line pressure acting in opposite directions.

Elbow pressure balanced expansion joints are designed to compensate for axial movement due to these external forces, thereby protecting the system. 

Hyspan, a world leader in the manufacture of bellows expansion joints, packed slip expansion joints and ball joints for industrial applications. Hyspan produces a complete line of flexible tubular products that meet the needs of diverse industries ranging from scientific research to oil refining.

The image above of a 24” NPS Hyflex pressure balance universal elbow expansion joint that is almost 15 feet long used in a geothermal power plant illustrates their ability to engineer and manufacture custom products to meet any need.

For more information about expansion joints or Hyspan products, contact Piping Specialties, Inc. by calling 800-223-1468 or visit their web site at https://psi-team.com.

We Take Pause and Thank Our Veterans


Veterans Day is not just another holiday. It honors those Americans who fought for our freedom. By celebrating our Veterans, we continue to tell the story of how this country became the most powerful on Earth - through bravery, honor, truth, and determination. 

Our Veterans are our neighbors, friends, family, and co-workers. They took an oath to defend the United States and our Constitution, from all enemies, foreign and domestic. We must never forget their bravery, service, and sacrifice.

PSI/Piping Specialties thanks our Veterans for serving our country and protecting our freedom.
