Pressure Relief Valves

Pressure Relief Valves

Our Pressure Relief Valves are designed to protect industrial piping systems and vessels from over pressure. These valves begin to open as there is an increase from the set pressure. The safety relief valves open completely on achieving the set pressure mark and continue to open further, thus allowing more flow. When the pressure level falls below the set pressure, the valve closes again.

Three functional elements of a HVAC pressure relief valve:

  • Valve element – It is typically a spring loaded poppet valve
  • Sensing element – It is a piston or a diaphragm
  • Reference force element – It is usually a spring

When selecting a pressure relief valve, special care must be taken as it must be capable of passing enough flow to relieve the system from over pressure. We, at Evergreen Midwest Co., recommend customers browse through our stock of Atmospheric Pressure Relief Valve, Straight Through Pressure Relief Valve, Female Connection Pressure Relief Valve to select the one that serves your specific purpose.
