ZZYP self pressure pressure reducing valve, Wenzhou self operated pressure reducing valve, specializing in the production of self operated pressure reducing valve size / quotationDetailed description:
Engineering valve ZZYPSelf operated pressure reducing valveSummary
ZZYP self pressure pressure reducing valve is a kind of external energy without need, using the controlled medium own energy, when the power source, the introduction of the implementation of the membrane chamber to produce thrust, control the movement of the throttle components 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.

Note: 1. pressure closed type is used for pressure regulation after valve. When the pressure rises after valve, the valve closes, so as to achieve the purpose of reducing pressure and stabilizing voltage.
2. press opening for the valve after the pressure adjustment, when the valve after the pressure rise, the valve open, in order to achieve pressure relief, the purpose of voltage regulator.
