fire fighting gate valve,
fire check valve
By pressure transmission of the main valve with a small change in the pilot valve size and adjustment.
Installation: horizontal, vertical installation for more information please contact us.
When the downstream water supply needs, the solenoid valve open, acting on the main valve reduces the pressure on the film along with the main open the valve.
When the downstream water supply to be stopped, the solenoid valve closed closed, the upstream pressure on the film in the main valve, the main valve closed.
This vavle is suitable on system such as petroleum, chemical industry, foodstuff, medicine, papemaking, water and electricity, shipping, plumbing, the smelting and sources of energy etc the pipe route. Can regard on gas, liquid, semifluid as well as solid powder pipes and power lines and the container of many kinds of corrosiveness and non-corrosiveness adjusts and dams a river the equipment use. Especially extensively being in high layer of building fire protection system reaches other to show in the pipes and power lines system of valve of vavle switch state.
