Tianjin Huayang Valve Co., Ltd products

Utile prossuro loss: water loss is £oro ai full open, completely smooth How. which will noi be deposited oh dielectric valve cavity. Bears the particles attrition: V shape opens the mouth between the ball crown and the metal valve seat the action is shear, m the closure process. only then depends on in last the moment ball crown to the valve seat, does not lorm the friction, also ihe valve seat makes with the wear -resisting nickel alloy. is not easily washed out the attrition, thus is suitable to contains the textile fiber, the small solid panicle, the thick liquid and so on.

Rubber lined buttertly valve is a kind ot valve with thick polymer lining on the body and disc. The lining makes ihe body completely isolate from medium and provides excellent anti-corrosive performance. It is designed as a device to shut-of (or regulate the working medium (low and installed in pipelines  or vessels with medium of acid, alkali . salt and oxidant, reducing agent, organic solvent in chemical, petroleum, pharmacy, lood. iron and steel smelting.  paper making, water power plant etc. It can be served as gate valve, globe valves as well as other shutting ot( or regulating valves.
