The 30d13y 30d13r Pilot-operated (before Valve) Pressure Control Valve

we are offering The 30d13y 30d13r Pilot-operated (before Valve) Pressure Control Valve.
Summary
The 30D13Y30D13R 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
