OEM Manual ductile iron unidirectional soft sealing wafer knife gate valve factory

Unidirectional soft sealing knife gate valve is actually one kind of gate valve. It works same like the gate valve, can only be fully opened and closed, and cannot be used for regulating and throttling. There is one blade like cut at the bottom of the valve plate of the manual unidirectional soft sealing knife gate valve, which move up and down perpendicular to the flow direction of the medium. When the blade-like valve plate moves up, the knife gate valve opens, and the medium can flow through. When the blade-like valve plate falls down, the knife gate valve closes, and the medium flow will be cut off. 

With different sealing material used, knife gate valve can be divided into soft sealing knife gate valve and metal hard sealing knife gate valve. Soft sealing knife type gate valve is also called resilient seated soft sealing knife gate valve. 

While for soft sealing knife gate valve, there are unidirectional soft sealing knife gate valve and bidirectional soft sealing knife gate valve. Today we are going to introduce the ductile iron unidirectional soft sealing wafer knife gate valve.
