ZZYP-16CK cast steel self operated pressure regulating valve steam gas air liquid water pressure difference control valve

 

 

Self operated pressure regulating valveSummary

    ZZYPtypeSelf operated pressure regulating valveIt does not need additional energy, uses the energy of the controlled medium as the power source, introduces the actuator to produce thrust, and controls the movement of the throttling element to achieve automatic adjustment. Comprehensive functions of measurement, execution and control. It can be used in places where there is no gas or electricity. Widely used in petroleum, chemical, power plant, light industry, printing and dyeing industry department automatic control system in various equipment gas, liquid and steam medium deceleration pressure, pressure regulator (used for after the valve pressure adjustment) pressure relief, pressure regulator (used for valve front pressure regulation) automatic control. According to the different working conditions of users, different valve core structure types and different actuators can be chosen to achieve the best control effect.

Pressure closed type: for the valve after the pressure adjustment, when the valve after the pressure rise, the valve closed, in order to achieve the purpose of decompression, pressure.
Press opening type: used for pressure regulation after valve, when the pressure rises after valve, the valve opens, so as to achieve the purpose of releasing pressure and stabilizing voltage.
