The 30d04y 30d04r Self-operated Differential Pressure Control Valve

We are offering the 30d04y 30d04r self-operated differential pressure control valve.
summary
the30d04y30d04r self-operated differential pressure control valve is composed of the control valve ，actuator and a spring used for pressure setting。
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.various combined controls can be carried out through the assemblies
