Product overview

Zzyp self operated pressure regulating valve is mainly composed of control valve, actuator and a set pressure spring. It is suitable for pressure control of non corrosive liquid, gas and steam in front of the valve (when the pressure in front of the valve increases, the control valve opens) or behind the valve (when the valve pressure rises, the control valve opens). It is widely used in petroleum, chemical industry, electric power, metallurgy, medicine, food, textile, machinery, HVAC. The action types are pressure regulation after pressure reducing valve (type b) and pressure regulating before pressure relief valve (type K).

Features of self operated pressure regulating valve:
 
Compared with manual control valve, self operated pressure regulating valve has the advantage of automatic regulation; compared with electric control valve, its advantage is that it does not need external power. The self operated regulating valve relies on the pressure and temperature of the medium flowing through the valve to drive the valve to work automatically without external power supply and secondary instrument.
Function of self operated pressure regulating valve:
 
The feedback signals (pressure, differential pressure and temperature) from the valve output end are transmitted to the actuator through the signal pipe to drive the valve disc to change the opening of the valve, so as to achieve the purpose of regulating the pressure, flow and temperature. In the closed water circulation system (such as hot water heating system, air conditioning chilled water system), the correct use of this valve can easily realize the flow distribution of the system, realize the dynamic balance of the system, greatly simplify the debugging work of the system, and stabilize the working state of the pump.
