ZHD Series (Magetsi kana Pneumatic) Minimum Flow Control Valve
ZHD multistage cage control valve yakashandiswa multilevel cage symmetric sleeve contol valve. Iyo inokwana kudzora svikiro velocity mukati mevharuvhu, uye yakadzikisira zvakanyanya ruzha rwunoitwa neakakwira gasi kana chiutsi mukati mevharuvhu, yakadzikama multistage kudzvanywa kudzikisa kuderedza inoshanda kudzivirira mvura cavitation, saka ndiyo yakagadzikana yekudzora vharafu inoshandiswa mu-high-pressure medium performance, vatengi vanogona zvakare kusarudza akawanda. -spring disphragm mechanism kana pneumatic actuators, nezvimwe.
