Wedge gate valve for coal gas  is a kind of  double wedge disc gate valve ,which is widely installed in the coal gas pipe line in the steel industry . It is suitable for coal gas ,burning gas ,sometimes it contain ash and CO. 

Benefits

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. Double wedge gate valve can keep sealing safe and reliable when  coal gas  supply is checked.

3.The high precision of the valve stem realizes the tight integration with stuffing .So, medium leakage can be avoided.

4.Rising type valve stem are adpot . 

5.Ex type electric actuator save a lot of labour work .
