Types of Pressure Valves

Browse pressure regulating and relief valves at Stockpile Express and find essential components for your plumbing, heating, or piping system. Whether your goal is safety or function, choose from the primary types of pressure valves to suit your needs:

  • Both pressure reducing and pressure regulating valves are used to control the flow of liquids or gas through pipes in a given heating or plumbing system. Pressure reducing valves are commonly associated with liquids, while regulators are used for gases.
  • Pressure relief valves vent a device when it reaches a preset pressure, preventing damage to the system. Unlike pressure reducing and regulating valves, which help a system function as intended, pressure relief valves serve as a crucial safety feature.

Browse high-quality pressure valves from Watts, Honeywell, Bell & Gossett, and other trusted brands at Stockpile Express.

Frequently Asked Questions

What is the difference between a pressure relief valve and a regulator?

Pressure regulators, or regulating valves, control the flow of gas in pipes or tubes within a heating or plumbing system, keeping pressure at a constant, preset level. Pressure relief valves, in contrast, vent a device to avoid overpressure and prevent damage to the system.
