The closure member of the wedge gate valve is wedge disc. Besides the flow control on water, steam, oil, gas and other corrosive medium, the pneumatic gate valve can also be used in the environment with high temperature and high pressure.
Features
1. Manufactured with straight-through passageway, the energy loss is less than that of the S shape passageway since 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 big loading coefficient of sealing. Safe and reliable, 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.
