Hydraulic station Control Slow Shut Non return Butterfly Valve is mainly installed at inlet pipe of water turbine; or installed at outlet side of all kinds of pumps, replacing check valve and gate valve. This valve will cooperate with main device in the pipeline, through hydraulic station, electric actuator PLC setting, to achieve reliable cut-off function and eliminate water hammer. It can automatically close when power goes off so to protect the pipeline system.
This couterweight type model is automatically cut off by gravitational potential energy of the couterweight hammer. It is applied with PLC control system. It can also assemble with munual locking and automatic locking device.
