Pneumatic shut‑off valves use compressed air as power source to realize rapid emergency cut‑off and on‑off control of pipeline media. Featuring fast response, good sealing and high safety, they can be remotely controlled with solenoid valves.

Widely used in petrochemical, natural gas, power plant, metallurgy, pharmaceutical and gas industries under flammable‑explosive and high‑risk conditions. They close quickly in emergencies to cut off medium delivery, preventing leakage, explosion and fire for production safety.
