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.

Choke valves are widely used to adjust pressure and flow. Jereh choke valves include the hydraulic and manual in respect of the operation mode. Adjustable choke valves adopt union connection and the orifice size is adjusted to achieve the regulation of flow and pressure.

Pressure relief valves act as a fail-safe for reciprocating plunger pumps, pressure vessels and testing lines, etc. The open/close pressure is controlled by belleville washers. When the pressure exceeds the preset limit, the valve will release pressure automatically. When the pressure drops below the preset limit, the valve will close automatically to protect the personal and equipment safety. Jereh pressure relief valves feature high strength, wide pressure range and stable performance. The pressure containing parts are forged from premium alloy steel and the metal melting and heat treatment process guarantee the hardness and strength. Various belleville washer stack configurations are available for different pressure ranges. The special treatment of the pressure relief mechanism provides stable sealing performance. To meet diverse customer needs, Jereh offers pressure relief valves suitable for cementing, acidizing, fracturing and testing lines. Customized design is also available.

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.
