Summary
The*0D*2Y/*0D*2R pilot-operated (after
valve) pressure control valve is composed of the control
valve,pilot
and actuator .It is suitable for controling differential pressure
in the pipes of non-crrosive liquids, gases and steams. when the
diferential pressure rises, the control valve is closed
.
The main features are as follows:
