Product Description

Manual Operating Type WCB Knife Gate Valve  is specially designed for the flow control in coal dressing, sewage treatment, food, medicine and other industries. 

Benefits 
1. Quite short in structural length, and less material, reduce the overall weight of the pipeline system; 
2, This sluice valve requires smaller space and knife gate valve can effectively increase the pipeline strength and reduces possible vibration. 
3, Valve disc made of stainless steel has higher corrosion resistance and can effectively avoid leakage caused by corrosion of the disc. 
4, PTFE material is adopt as upper sealing which is highly reliable. 
5, Serving like a knife switch, this industrial valve can cut off sundries from the fluid.
