fire fighting gate valve,
fire check valve
Signal gate valve often used in automatic sprinkler fire piping system to the critical control and water supply pipes, remote indication of valve opening. Rising Stem Gate Valve and attached to the opening direction gate valve are often used in fire protection system, if the gate valve installation location away from the high ground, usually I lever gate valve, it is clear indication the valve opening, if the installation position of the lower. Gate valve is required to pay to open instructions.
Rising stem resilient seated gate valve, gate valve as a whole package glue to produce the phenomenon of deformation compensation effect to achieve a good sealing effect, to overcome the general valve seal bad, water leakage and rust the more effectively to save installation space. Can be widely used as the regulation and closure devices for water, sewage, construction, petroleum, chemical, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy systems and other fluid pipeline.
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.
