Brief introduction
this kind of product is widely used in the industry pipeline of flow medium as throttling and adjusting the flow volume, such as petroleum, chemical,metallurgy,electric, papermaking,heat power, water supply and drainage,especially used in transporting the medium containting of grain, dust and fibre etc

Features
1.thorough construction, small pressure, high efficiency and saving energy.
2. the reasonable eccentric construction determines the reliable metal-seated performance
3.the high hardness sealing surface makes the valve have predominant cutting ability and shear the reinforcing steel bar and basketwork when the valve shut off.
4.Rapid opening and closing, quarter-turn,small moment and convenient operation
5.the sealing surface is wear proof, corrosive resistant and long life for using
6.compared with the gate valve and old type ball valve, if has the virtues of small volume,light weight and convenient installation.
