Rotary Disc valve
Rotary Disc valve
Rotary Disc Valve and Rotary Gate Valve is mainly used for pneumatic ash handling systems of thermal power plants and designed for pressurized and vacuum systems including dense and dilute phase pneumatic conveying systems (systems like positive pressure dense phase, low positive pressure and negative pressure). Rotary Disc valve is a quick open/close valve that realizes opening/closing through a rotary disc. It is designed especially for the abrasive and erosive medium. Valve used at discharge, inlet and venting applications.
The self-grinding function of its particular hard sealing face allows its tightness to be improved increasingly during the application with abrasive and erosive materials, making its service life several times longer than that of other valves. Its disc, seat and body are separate structures connected with bolts, facilitating maintenance and replacement and reducing costs for operation and maintenance
