Gate valve WCB Introduction

The cast steel flange hard seal gate valve is mainly used for cutting off in the pipeline. This valve is widely used in petrochemical, thermal power plants and other oil and steam pipelines as opening and closing devices to connect or cut off the medium in the pipeline.


Features of Gate valve WCB

1. Low flow resistance;

2. Less effort when opening and closing. Compared with the globe valve;

3. Large height, long opening and closing time;

4. Water hammer is not easy to produce. The reason is the long closing time;

5. The medium can flow in any direction on both sides, easy to install. The two sides of the gate valve channel are symmetrical;

6. Simple shape, short structure length, good manufacturing technology and wide application range.


Advantages of  Gate valve WCB:

The fluid resistance is small, and the sealing surface is less brushed and corroded by the medium. It saves effort to open and close. The flow direction of the medium is not restricted, does not disturb the flow, and does not reduce the pressure. Simple structure, short structure length, good manufacturing technology, many optional materials for high temperature and high pressure resistance, and wide application range.
