ZCM zero differential pressure coal gas valves(pic1)
ZCM zero differential pressure coal gas valve(pic2)
medium： coal gas,methane, gas,natural gas, normal temperature liquid,gas
product feature
apply to two way type on and off switch piperoad with coal gas flame medium reach aotumatic and long distance control temperature
structure feature
1, direct acting -style open valve structure, without differential pressure limit, low pressure or zero can normal open and close, without pressure loss, low pressure with large flow.
2, using high quality materials,for the body sealing without leakage. Is the ideal actuator forliquid gas.
3, form: normal closed type.
Special supply
DN: 32 following specification, also can provide flange connecting flange type. In places with explosive, with explosive godfathers, explosion-proof level: dIIBT4
2 and explosionproof qualification certificate: GYB01272
