IMI Bopp & Reuther PC 50
The controlled safe pressure release system is primarily used when standard spring-loaded safety valves cannot meet strict operating conditions.
In addition to the safety valve spring, the controlled safety valve is equipped with an air cylinder piston. The PC 50 operates on the closed-circuit principle, i.e. the charge air is discharged by measuring the coupling pressure (usually set pressure). Five piston sizes are available that can be combined with all safety valves from DN 25 to DN 400.
The loading air increases the closing force to the set pressure and the lifting air supports the blow-off process. The fail-safe function of the safety valve are ensured by installed spring loads, even in case of air failure. More than one safety valve can be used with one control unit.
There is static performance, e.g. increased tightness to valve opening, high setting accuracy and precise repetition of set pressure, improving operating efficiency.
Typical applications are systems with high operating pressures, increased tightness requirements, limited opening and reseating parameters and critical applications.
For nuclear applications, the control unit PC 50 is available in a stainless steel housing with reinforced superstructure. This design is dynamically qualified for 3g, including fundamental frequency test.
