Pressure Regulating Valves are available in bronze, cast-iron and ductile-iron and are designed for steam, air, and liquid service. These regulators can handle inlet pressures up to 450 psig and are available in threaded and flanged connections.

Relief and Back Pressure Valves are typically used for water pump bi-pass, sprinkler systems, fountains, irrigation, and fire protection systems.

  • Materials: Bronze & Cast Iron
  • Max Inlet Pressure: 300 PSI
  • Sizes: 1/2" - 3"

Self-Operated Temperature Regulating Valves for Heating and Cooling
The 175 and 153 Series Self-Operating Temperature Regulating Valves require no external power source making them easy to install and maintain.

  • Temp Range: 20° - 250°F
  • Sizes: 1/2" - 4"

Pressure Regulators

Regulator

O Series

Pressure Regulating Valve - STEAM, Water, Air, Oil, other Liquids & Gases 
The O Series, with Cast Iron body and Hardened Stainless internals, is our most popular and economical solution for reducing pressure in STEAM systems. It will also handle Air, Water, Oil as well as other Liquids and Gases. 

B Series

Pressure Regulating Valve - WATER, Air, Oil, other Liquids & Gases
The B-Series is primarily used for reducing pressure in WATER systems. It will also handle Air, Oil, as well as other Liquids and Gases. The B-Series is higher capacity than the O-Series, however it will not handle the temperature requirements of Steam. 

455 Series

Pressure Regulating Valve - STEAM, Air, Water, other Gases
The 455 is used for reducing pressure in STEAM applications and require only 5 PSIG minimum inlet pressure (HD regulators require minimum 15 PSIG). Excellent for use in steam systems that contain large amounts of scale that may cause failure in pilot-operated regulators. With a slight modification to the internal mechanism, the 455 can be used for Liquid systems. 

402/403 Series

Pilot-Operated Regulating Valve - STEAM, Air
The 402 is a pilot-operated, piston-actuated, pressure regulator used for reducing pressure in STEAM systems. This regulator can be equipped with an optional internal sensing line which simplifies installation. The 403 Series has all stainless steel internals for high-pressure applications.

 

Back Pressure-Relief Valves

R Series

Relief and Back Pressure Valves - Water, Liquids
The R Series is an economically-priced Back Pressure Relief Valve for Liquid service. Relief Valves protect systems from over-pressurized conditions. 

3040 Series

Relief and Back Pressure Valves - Water, Liquids
The 3040 Back Pressure Relief Valve has a much higher capacity than the R Series. Used for Liquid service. Relief Valves protect systems from over-pressurized conditions. 

 

Temperature Regulating Valves

175 Series 

Heating

153 Series

Cooling

Self-Operating Temperature Regulating Valves - Heating/Cooling
The 175/153 Series temperature regulating valves are used for controlling temperatures in industrial and HVAC applications.
