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