The upstream pressure P1 shall enter into the upside of piston control chamber through ball valve and control tube. The upside of piston control chamber will communicate with downstream through pressure reducing pilot valve and control tube. The underside of piston control chamber communicates with the outlet of valve. The downstream pressure P2 shall be set by adjusting the bolt of pressure reducing pilot valve. When the upstream pressure P1 and flow are varying, the opening of main valve can be controlled by fluctuation of the sensitive components piston regulated by pressure reducing pilot valve so as to ensure the downstream pressure P2 to be constant.
