Summary
The *0D*3Y/*0D*3RÂ pilot-operated
(before 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
opened The main features are as
follows:
1.It has the pressure balancing function
with high sensitivity.
2.Low noise, reliable performance, free
of maintenance
3.The standard modular design is
adopted.
4.High control precision
