Product overview

Signal gate valve is often used in automatic sprinkler fire pipeline system to monitor the water supply pipeline and remotely indicate the valve opening.

The rising stem gate valve and the gate valve with opening indication are also often used in the fire protection system. If the gate valve is installed at a higher position on the ground, the rising stem gate valve is generally used to clearly indicate the valve opening. If the installation position is lower. A gate valve with opening indication is required.
