Tank Emergency Shut-off Valves
The primary purpose of internal tank storage valves is to ensure emergency shut off of storage tanks if they become damaged. SchuF was the original inventor of shut off valves for tank storage.
Applications - Emergency Shut Off Valves
The primary application of emergency shut off valves is to ensure the safety of storage tanks containing dangerous fluids such as LNG, Chlorine, VCM, VC, Propane, Propylene, or Ammonia. Safety conscious companies specify shut-off valves with an in-lying seal.
