Special Fire Signal Resilient Seated Gate Valve

Summary

Signal gate valves and signal butterfly valves are used in automatic spraying water pipeline in fire protection system to monitor the water supply pipeline and indicate the valve's opening at a long distance. Rising stem gate valves and opening indicator gate valves are often used in fire protection system, and if the installation position is high to the ground, rising stem gate valves is used and can show the valve's opening clearly while if the installation position is low, opening indicator gate valves is used.
