Straight-through casting pressure self-operated control valve

ZZPY Self-controlled micro pressure regulating valve（Description）

ZZYP self-pressure regulator is mainly composed of a control valve, actuator and a set pressure spring, suitable for non-corrosive liquids, gases, and steam, in the system pipeline before the valve (when the valve pressure increases, the control valve open) or after the valve (when the valve pressure increases, the control valve open) pressure control. Widely used in petroleum, chemical, electric power, metallurgy, medicine, food, textile, machinery, HVAC. The action types include post-valve pressure regulation for decompression (type B) and pre-valve pressure regulation for pressure relief (type K).

Features of self-operated pressure regulating valve:

Self-actuated pressure regulating valve compared with manual regulating valve, its advantage is to be able to adjust automatically; Compared with the electric control valve, its advantage is that it does not need external power. Self-regulating valve depends on the pressure and temperature of the medium flowing through the valve itself as energy to drive the valve to work automatically, without external power supply and secondary instrument.

Function of self-operated pressure regulating valve:

Self – control valve use valve output feedback signal (pressure, differential pressure, temperature) through the signal pipe to the actuator drive valve disc to change the valve opening, to adjust the pressure, flow, temperature purpose. In the closed water circulation system (such as hot water heating system, air conditioning chilled water system), the correct use of this valve can be very convenient to realize the flow distribution of the system; It can realize the dynamic balance of the system; Can greatly simplify the system debugging work; Can stabilize the working state of the pump.
