SOT Sempell Model SOT Design With Welding End Or Flanged Connections High Pressure Steam Safety Valve

SOT Sempell Model SOT Design With Welding End Or Flanged Connections High Pressure Steam Safety Valve

High pressure safety valve for boiler protection in disc spring design with welding end or flanged connections

Features

High tightness up to set pressure due to supplementary load
Smooth operation (no forces by popping)
Disc spring allows higher forces compared to helical spring. This results in high set pressures even for high capacities.
Mechanical lift stop ensures functional stability
Locking for hydrostatic test without additional parts
High allowable back pressure

Applications

EN12952 and TRD boilers. Saturated super-heated and super-critical steam. Also suitable for specific gas applications where full control is required.

These Controlled Safety Pressure Relief Systems (CSPRS) use an actuator to provide perfectly controlled performance in pressure protection in full compliance of EN and TRD requirements. These valves can be fully customized to perfectly suit the requirements of the application for seat tightness, overpressure and blowdown performances. Helical spring (Type SOH) or disc spring (Type SOT) for larger valves. Combined with STE4 electro-pneumatic control unit or STE5 pneumatic control unit, with redundances and in-line checks. TÜV type-tested to PED & EN4126-5.
