Operation:
1． Manual actuation
In most cases,resilient seated gate valve are operated by handwheel or a cap top using a T-key.TWS offer handwheel with the right dimension according to the DN and operating torque.Regarding cap tops,TWS products comply with the different standards;
2． Buried installations
One special case of manual actuation occurs when the the valve buried and the actuation has to be done from th surface;
3． Electrical actuation
For remote control,allow the final user to monitor the operations of the valves.
