ZZYP Automatic pressure control valve

ZZYP automatic pressure control valvedepends on the pressure change of controlled media to get the steady state value ofupstreamor downstream pressure automatically,which is an energy efflcient type control valve without external energy.  Itls an ideal energy efficlent type control valve,which ls widely used in various industies for the holding and stable of medla which the pressure between upstream and down-stream is less than 1.6MPa.For theoccasions of corroslve,Jow viscosity and even the dowistream pressure is more than 20MPa,this valve can be used  after belng speclally treated.
