Gb Wedge Gate Valve

Wedge gate valve adpot wedge disc as closing part ,it is widely use in water, steam, oil, gas and other corrosive medium. The gate valve can also be used in the environment with high temperature and high pressure. Features 1.Manufactured with straight-through channel, the energy loss is less than that of the S type channel, the flow direction of the medium is not changed when passing through the gate valve. 2.The wedge structure of the valve plate makes for large loading coefficient of the sealing. Safe and reliable ,so this wedge gate valve can be used under high pressure. 3.The high precision of the valve stem realizes the tight integration with stuffing .So, medium leakage can be avoided.
