Signal gate valves are often used in automatic sprinkler fire line systems to monitor the water supply lines and indicate the valve opening remotely.

The lift type gate valve and the opening indicator valve are also often used in the fire control system. If the installation position of the gate valve is higher from the ground, the lift rod type gate valve is generally used, which can clearly indicate the opening of the valve. If the installation position is low, the gate valve is required with the degree of opening.
