ZZYP-16CK cast steel self pressure regulating valve of steam air liquid pressure difference control valve

 

 

Self pressure regulating valveSummary

    ZZYPtypeSelf pressure regulating valveIs a kind of no external energy, the use of controlled medium energy, when the power source is introduced to perform the membrane chamber thrust control, throttling element movement to achieve the automatic adjustment. Comprehensive functions of measurement, control and execution. No gas, no power can be in place. Widely used in petroleum, chemical, power, light industry, printing and dyeing industry in the automatic control system of various equipment of gas and liquid and steam medium pressure reducer, regulator (for pressure regulating valve after the pressure relief), voltage (for the valve before the pressure adjustment automatic control). According to the different working conditions can be made of different types and different valve actuators, in order to achieve the best control effect.
