Ammonia valves are specially designed for liquid ammonia and gaseous ammonia media, featuring low‑temperature resistance, ammonia corrosion resistance and reliable sealing.

They are widely used in cold storage refrigeration systems, ammonia refrigeration units, chemical fertilizer production, coal chemical industry and liquid ammonia transportation pipelines for cut‑off, regulation and backflow prevention, ensuring safe operation of low‑temperature, toxic, flammable and explosive ammonia systems.
