The spring pushes down on the disc to create a seal with the nozzle that lifts at the valve set point. SpringDiscNozzle How does a Safety Valve work? Stellar Industrial Technologies

How does a Safety Valve work? A Safety Valve is a very simple device. Two pieces of metal are squeezed together by force provided by a spring. When the counter pressure from below exceeds the spring pressure, the disc lifts, relieving pressure from the system. A Safety Valve is a very simple device. Two pieces of metal are squeezed together by force provided by a spring. When the counter pressure from below exceeds the spring pressure, the disc lifts, relieving pressure from the system. Stellar Industrial Technologies

SPRING The spring is used to hold the The spring is used to hold the nozzle and Disc together until the desired set point, at which the disc will lift off the nozzle and the valve will relieve. Stellar Industrial Technologies

Disc & Nozzle The disc is held tight against The disc is held tight against the nozzle by the spring to create a tight seating service. A common cause of valve leakage is debris or grit in the end users system scratching the nozzle or disc. Stellar Industrial Technologies

Trouble Shooting #1 reason– System operating pressure is too close to the valve’s set pressure. Safety valves require a 5 psi or 10% difference between the operating and set pressure (whichever is greater) for the valve to work properly. #1 reason– System operating pressure is too close to the valve’s set pressure. Safety valves require a 5 psi or 10% difference between the operating and set pressure (whichever is greater) for the valve to work properly. Stellar Industrial Technologies

Trouble Shooting EXAMPLE EXAMPLE A reducing valve reducing from 100 to 10 PSI A reducing valve reducing from 100 to 10 PSI The Safety Valve cannot be set any lower than 15 PSI. It would be better to set it at 20 or 25, depending on the pressure that the downstream vessels could handle. The Safety Valve cannot be set any lower than 15 PSI. It would be better to set it at 20 or 25, depending on the pressure that the downstream vessels could handle. Stellar Industrial Technologies

Trouble Shooting Is the valve mounted correctly? Most safety valves are designed to operate in a vertical position only. A valve mounted horizontally or upside down can not operate as intended. Stellar Industrial Technologies

Trouble Shooting Is the valve mounted correctly? Outlet piping should be supported by something other than the valve itself. If the piping is not supported it can strain the valve and cause the internals to align improperly Stellar Industrial Technologies

Troubleshooting Pipe dope or Teflon tape is often the culprit in leaking valves. When installed, care should be taken to ensure that it is not too low on the threads. If this gets into the valve, it can stick on the seating surface and cause a constant leak. Pipe dope or Teflon tape is often the culprit in leaking valves.

Troubleshooting Seating surface scratches Seating surface scratches Dirt/grit/debris from the system is most commonly the culprit in leaks if all other questions are answered. Dirt/grit/debris from the system is most commonly the culprit in leaks if all other questions are answered. This grit goes through the valve and scratches the nozzle, disc or both, causing an incomplete seal and the valve leakage.
