Forged from solid 316L stainless steel with precision inner polishing, the valve features outstanding resistance to acid, alkali, corrosion and high temperature. It can adapt to various harsh working media including high-purity gas, hydraulic oil, steam and chemical fluid to extend service life.

Rich connection types are optional, including double ferrule, NPT male thread, NPT female thread, ferrule to male/female thread. It matches seamless instrument tubes ranging from 1/8" to 1", which can meet diverse pipeline connection requirements in different working conditions.

Adopts mature double ferrule connection technology, no welding or raw tape required during on-site installation. After tightening the nut, the ferrules can firmly bite the outer wall of the pipeline to realize stable leak-proof connection, greatly reducing the risk of pipeline leakage caused by improper construction.

Strictly inspected through air tightness and hydraulic pressure tests before delivery to guarantee stable product quality. Widely applied in petrochemical, power plant, laboratory, new energy and hydraulic pneumatic industries, it is a cost-effective alternative to imported branded check valves.
