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

19. 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. Stellar Industrial Technologies

20. SPRING • 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

21. Disc & Nozzle • 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

22. Operation • Warn • Valve is ready to open • Pop • Valve opens • Blowdown • System Pressure has receded to below set pressure • Reseat Stellar Industrial Technologies

27. Valve Selection • Other Factors • Temperature • Corrosive media or environment • Back Pressure • Connections Stellar Industrial Technologies

28. 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. Stellar Industrial Technologies

29. Trouble Shooting • EXAMPLE • 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. Stellar Industrial Technologies

30. 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

31. 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

32. 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. Stellar Industrial Technologies

34. Troubleshooting • Seating surface scratches • 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.
