Product Description

Safety valves of this type are controlled by the medium flowing through it via a pilot valve.It is preferably installed in branches of supply pipework and protects downstream parts of a system which are at risk from unacceptable excess pressure which can, for example, be caused by pumps. If the inlet pressure to the valve rises up to the set opening pressure, then the valve opens immediately to the maximum flow position. If the pressure falls to the set pressure, then the valve closes slowly to prevent pressure shock loads.
