China Factory for Valve Calibration Machine - butterfly buffering check valve – GMK Valve
China Factory for Valve Calibration Machine - butterfly buffering check valve – GMK Valve Detail:
Butterfly buffering check valve Nominal pressure:PN1.0Mpa
Nominal diameter: DN200-2000mm.
1. The kind of valves are automatic type which are opened by the pressure of the medium and closed the revrsing flow, the better the sealing is and the higher the reversing flow pressure.
2. The water hammer rising has been taken into considerration during design, it is realiable.
3.It has damper device , it can regulate closing by quickly closing and slowly closing two stages, and the quickly closing time and the slowing closig time can regulate , it can prevent the dump or blower fan from reversing or the overload hammer pressure, in order to protect the system safety.
4 As it has no weight on the shaft, in the open position, all forces of the disk is balance, it can reduce the flow resistance.
The product has novel structure, small size, fluid resistance small, smooth operation, reliable sealing, wear resistance, cushioning performance and good features, is the best industrial water and sewage products.
The valve used for industrial water supply buffer, sewage treatment plants, pump outlet to prevent the pipe network upstream.
