CHFS series shut-off valve is a self-operated emergency safety shut-off valve, which is an important safety protection device in the gas transmission and distribution system. Its ultra-high (ultra-low optional) pressure cut-off function, can quickly cut off the gas flow when the system pressure reaches the warning value, to protect the safety of the downstream system. Especially suitable for high and medium pressure systems.
