Signal hard seal gate valve

Signal hard sealed gate valves are often used in automatic sprinkler fire pipeline systems to monitor water supply pipelines and remotely indicate valve opening. Elastic seat sealed signal gate valves and attached opening indication gate valves are often used in fire water supply systems. If the installation position of the gate valve is high above the ground, a rising stem gate valve is generally selected, and the valve opening indication can be clearly seen. If the installation position is low, the valve opening indication can be clearly seen. Then it is necessary to choose a gate valve with an opening indicator
