Signal gate valve and signal butterfly valve are often used in automatic sprinkler fire-fighting pipeline system to monitor the water supply pipeline and remotely indicate the valve opening.

Rising stem gate valves and gate valves with opening indication are also often used in fire protection systems, If the installation position of the gate valve is high from the ground, the rising stem gate valve is generally used, which can clearly indicate the opening of the valve. If the installation position is low. The gate valve with opening indication is required.
