Underground resilient seated gate valves used for fire fight is used in automatic water spray fire pipeline system to monitor water supply pipelines. It's kind of gate valves with opening indicator, if the installation position of the gate valve is high from the ground, commonly use the rising stem gate valves, which can obviously indicate the opening of the valve. if the installation position is low, it's needed to use gate valves with opening indicator. Fire-fighting underground resilient seat gate valves is 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.

Customized valves are acceptable. Hebei Quanyi Machinery Co., Ltd is able to design and produce standard and non-standard resilient gate valves.Available diameter range: DN40~DN 1100.
