Proportional Relief Valve - Schwer PRV
Summary

  • Stainless steel Proportional Relief Valve
  • Proportional relieve valve for pressure limitation in closed systems.
  • The spring sets (PSS1…) have to be ordered separately and can be selected between 50 and 6000 psi (3.5 to 413 bar),
  • NPT or U2 connection options.
  • The valve can be ordered with preset opening pressure on request.
  • European manufactured and distribution center.

Description Technical Specifications Downloads Vendor

Proportional Relief Valve - Schwer PRV

  • Common standard body design with ability to use one of 8 spring sets for different pressure ranges.
  • The valve opens when the set pressure is exceeded, but regulation proportional to the pressure increase, no sudden opening.
  • Pressure release until the nominal pressure is again below the setting pressure.
  • Nominal pressure is less than the setting pressure, Force of the spring is sufficient to close the system again.

Key features

  • Stainless steel valves
  • Less stress on the system, as there is no sudden relief, PRV is designed for repeat openings and release of pressure
  • Pressure ranges between 3.5 to 413 bar
  • NPT or U2 connections available
  • The valve can be ordered with preset opening pressure on request.
