Check valves are widely used in high pressure pipeline to control fluids flowing in one way and stop fluids from flowing back to the pump, protecting pipeline safety. Jereh check valves are available in three types including top-entry, dart and flapper. The top entry and flapper types adopt completely wrapped flappers to extend the service life, and they are mainly used in fluid services. Dart check valves feature dual seals between stainless steel and seal ring and they are mainly used in gas services.

Integral fittings are mainly used to connect components to form surface manifolds. Forged from high strength alloy steel, Jereh integral fittings have gone through advanced heat treatment and strict quality control before delivery. Jereh integral fittings adopt union or thread connection. Jereh integral fittings are available in many types such as tees, laterals, wyes, long radius elbows, elbows, crosses, adapters and plug unions. Customized design is also available.

Reel swivels are mainly used in coiled tubing units with one end connected to the coiled tubing and the other end connected to surface manifold to rotate under pressure. Jereh reel swivels feature excellent sealing capability and strong corrosion resistance. Special sealing configuration and components ensure higher sealing performance and longer service life. Key seal surfaces are treated specially to enhance corrosion resistance. To meet diverse needs, Jereh offers two basic types (U-shape and L-shape) both for standard and sour gas service. Customized design is also available.
