They are defined as a regional control valve. They are used as shut-off valves on water supply lines in order to separate(control) the zones inside the premises from each other. Butterfly valve or rising shaft valve is used for cutting or control purposes. Rising shaft valves are a type of gate valve that does not disturb the smooth flow in its fully open position, the open position can be monitored by eye with the movement of the shaft up and down, electrical monitoring can be performed by installing a tracking switch. They create less hydraulic loss with the ratio to butterfly valves.
