Mechanical pressure

Industrial and process pressure gauges

Mechanical pressure gauges are local gauges that simply detect pressure by flexing a mechanical sensor when the pressure changes. There are several types of sensors to suit almost any situation, there are several options to adjust the gauge to the specific needs of different processes or applications, such as compatibility with different liquids, overpressure protection and safety considerations, among others.

We adopt a multi-brand policy with the objective of offering a broad portfolio and benefits to our customers, allowing them to select the best mechanical pressure solution within high quality and price standards. Our brands are Galileo, Noshok, Wika and Winters.

Mechanical pressure accessories

  • Diaphragm seals / chemical diaphragm seals
  • Needle valves
  • Snubbers (pulsation dampers)
  • Siphon tubes (pigtails)
  • Needle valves and needle & bleed valves
  • 3-way and 5-way manifolds
  • Flushing rings
  • Others: adapters, bushings, panel mounting flanges, and laminated safety glass

Diaphragm seals or chemical seals

These are the right solution for measuring pressure when the fluid cannot enter a conventional gauge’s Bourdon tube, whether due to chemical incompatibility, viscosity, or a paste-like consistency.

We carry an extensive stock in AISI 316L stainless steel. We also offer chemical seals in PTFE, MONEL®, Hastelloy®, or Carpenter®. Any chemical seal can be supplied with a threaded, flanged, or sanitary-fitting process connection.

We use a Wika filling system, which guarantees the customer a perfect fill by achieving a total vacuum in the system, ensuring the fill fluid is free of air bubbles — which in turn ensures the proper operation of the gauge–seal assembly.

Needle valves

Block-and-bleed needle valves in 2-way and 3-way configurations are very important accessories in industrial plant instrumentation; one of their most common uses is allowing a pressure gauge to be installed and/or removed without stopping the process. The needle valves we keep in stock — in 316 stainless steel or zinc-nickel-plated carbon steel — are highly corrosion-resistant, feature a unique non-rotating stem tip, and are optimal for pressures up to 10,000 PSI. 3-way, 4-way, and 5-way manifolds, with an angular option for natural gas, differential pressure, and other applications. de nivel de líquido.
