RMR Series Pressure Relief Valve

 (88)
The SIMTECH RMR Series Pressure Relief Valve is a 2-port valve designed to relieve excess pressure that may occur in the line or system even with back pressure or head pressure on the downstream side. Adjust the threaded stem to obtain the selected line or tank relief pressure. An outlet (tee) may be required on the inlet side of the valve.

  • The valve starts to open as line pressure approaches set pressure until fully open.
  • The valve can be set to relieve excess pressure between 10-80 P.S.I.
  • The ¼” valve is also available with a relief range of 60-125 P.S.I.
  • It’s designed so there is no metal contact with the fluid and top entry makes in-line maintenance easy.
  • Can be factory ...

    RSB Series Diaphragm Pressure Relief Valve

     (72)
    The SIMTECH RSB Series Diaphragm Pressure Relief Valve is designed to protect piping and equipment from pressure changes where a rapid release of excess pressure is required. Prevents pumps from dead heading, over pressurization, pressure surge conditions, and maintains back pressure in closed loop systems.
  • Adjustable screw and lock-nut makes it easy to accurately preset desired relief pressure.
  • Teflon (primary) and EPDM (back-up) diaphragms standard.
  • No metal contact with fluid.
  • Wide adjustable relief pressure range (10-125 PSI)
  • Small pressure differential band from cracking point to fully open, and from fully open to close.
  • Top entry makes in-line maintenance quick and easy.
  • Ideal for DI ...

    RDR Series Low Pressure Diaphragm Relief Valve

     (12)
    Low Pressure Diaphragm Relief Valve (RDR) The SIMTECH RDR Series Low Pressure Diaphragm Relief Valve is designed for low pressure applications with no back pressure to release excess up-stream pressure on the piping, storage tank and/or system due to pressure surges, vaporizing, or heat reaction.
  • Adjustable screw and lock-nut makes it easy to accurately pre-set relief pressure.
  • Teflon (primary and EPDM (back-up) diaphragms.
  • This pressure relief valve is designed to keep the stainless steel spring totally isolated from the fluid chamber insuring no metal contact with the fluid.
  • Working pressure range from 5 to 25 PSI
  • Top entry and parallel inlet and outlet ports to facilitate installation and avoid ...

    RPB Series Pressure Bypass Valve

     (66)
    The SIMTECH RPB Series Pressure Bypass Valve is a 3-port valve designed to relieve excess fluid pressure in piping systems. When mounted in-line, the pressure by-pass valve will permit fluid to pass through the system. When the fluid pressure approaches the valve setting, the excess fluid is vented through the bottom port.
  • Adjustable screw and lock-nut makes it easy to accurately pre-set relief pressure.
  • Wide working pressure range (10 to 80 PSIG)
  • Top entry for easy in-line maintenance and can be factory pre-set upon request.
  • No metal contact with fluid

    Note: This valve is not designed to be used in piping systems with back-pressure on the downstream side.

    RNB Series No LubePressure Bypass Valve

     (66)
    The SIMTECH RNB Series Pressure Bypass Valve is a 3-port valve designed to relieve excess fluid pressure in high purity applications where lubrication is not permitted. When mounted in-line, the pressure by-pass valve will permit fluid to pass through the system. When the fluid is vented through the bottom port.
  • Adjustable screw and lock-nut makes it easy to accurately pre-set relief pressure.
  • Wide working pressure range (10 to 80 PSIG)
  • Top entry for easy in-line maintenance and can be factory pre-set upon request.
  • It is ideal for DI water and other highly purity piping systems as well as most harsh chemicals and corrosives.
  • No metal contact with fluid

    Note: This valve is not designed to be ...
