CLA-VAL 50-55F : Pressure Relief Valve with High Opening Speed and Progressive Closing Speed
The CLA-VAL 50-55F is typically installed in a main line by-
pass and discharges any overpressure produced eventually
at starting or stopping of the pump(s). When pumping
system is started and stopped gradually, harmful surges
does not occur. However, should an electric power failure
take place, the abrupt stopping of the pump(s) can cause
dangerous surges in the system which could result in
severe equipment damage.
The CLA-VAL 50-55F damps the respective overpressure
and prevents any additional surge build-up by its controlled
closure.
