BPV Back pressure regulator

Function
Even the optimal and sophisticated pressure reduction of the SCHROEDAHL automatic recirculation valves and control valves set extreme conditions limits in some installations.
SCHROEDAHL back pressure regulators type BPV are used in such cases.
They increase the distance to the evaporation pressure of the medium by generating a defined pressure difference. This prevents unwanted evaporation and cavitation and ensures smooth and gentle operation.
Careful adjustment of the operating parameters between minimum flow or control and back pressure valves ensures optimum system operation.
The pressure difference at the back pressure valve as specified in the design shifts the bushing (item 204) in the direction of flow against the pressure spring (item 237). This releases the throttle cross sections at the bushing until the specified pressure difference is attained.
