ZHD Series (Electric los yog Pneumatic) Yam tsawg kawg nkaus Flow Control Valve
ZHD multistage tawb tswj valve siv multilevel tawb symmetric tes tsho contol valve. Nws ua tiav tswj qhov nruab nrab nrawm nrawm nrog lub valve, thiab txo qis suab nrov ua los ntawm kev kub siab roj lossis chav nyob hauv lub valve, ruaj khov ntau theem siab txo kom tsis txhob muaj cov kua cavitation, yog li nws yog qhov ruaj khov tswj valve siv nyob rau hauv high-pressure nruab nrab kev ua tau zoo, cov neeg tuaj yeem xaiv ntau yam. -spring disphragm mechanism lossis pneumatic actuators, thiab lwm yam.
