Product Description

ZZYP self-operated regulating valve, self-operated differential pressure valve
ZZYP self-operated regulator, self-operated differential pressure valve
Overview of ZZYP type self-reliant pressure regulator
ZZYP type self-reliant pressure regulating valve without external energy, the use of the medium's own energy as the power source into the actuator control spool position, bend the difference of pressure and flow at both ends, so that the valve before (or after) pressure stability. It has the advantages of sensitive action, good sealing, small pressure set point wave power and so on. It is widely used in the automatic control of gas, liquid and steam medium decompression and pressure regulation or pressure relief and pressure regulation. Self-reliant pressure regulating valve has single seat pressure regulating valve (ZZYP), sleeve pressure regulating valve (ZZYM), two seat pressure regulating valve (ZZYN), three kinds of structure; The actuator has film type, piston type two; The type of action has the pressure adjustment after the decompression valve (type B) and the pressure adjustment before the pressure relief valve (type K). The nominal pressure grade of the product is PN16, 40, 64; Valve body caliber range DN20 ~ 300; The leakage level has three grades: II, IV and VI; The flow characteristic is fast opening; The pressure is adjusted in segments from 15 to 2500Kpa. Can be combined according to the need to meet the requirements of user conditions.
