Thin film belt self operated pressure regulating valve, high sensitive micro pressure regulating valve, high temperature steam of pressure reducing valve

 

 

 

The operation of type ZZHP ldirectord self pressure regulating valve, is a need of external energy, and only rely on an energy saving pressure is adjusted pressure medium itself to automatically adjust and stabilize the valve after the pressure of constant pressure regulating valve set in command, for convenience, under the condition of continuous operation time can be set; the control precision is high, than the general ZZY direct operation of self pressure regulating valve is twice as high, suitable for the control of high precision applications; detection and implementation of components made of high temperature resistant materials, without a condenser can also be used for high temperature (200 DEG C) steam occasions.
