Choke Valves are mainly used to adjust flow and pressure in the pipeline by changing the choke area, with union connections on the ends. Jereh Choke Valves can be divided into manual and hydraulic.

Safety Valves act as a fail-safe for reciprocating plunger pump, pressure vessel and testing lines, etc. The open/close pressure is controlled by spring washer. When the pressure exceeds preset limit, the valve may automatically unload. When the pressure drops below preset limit, the valve may automatically close to protect people and equipment. Jereh Safety Valves feature high strength, wide pressure range and stable performance. Jereh Safety Valves are forged from premium alloy steel, handled by advanced metal melting and heat treatment technology. Different number combination of spring washers allows wider pressure adjustment range. Pressure relief device realizes stable seal. To meet various demand, Jereh has developed many types suitable for cementing, acidizing, fracturing and testing lines. Customized service is also available.

Jereh swivel joints are forged from premium alloy steel, handled with advanced metal melting and heat treatment technology to ensure strength and hardness. Based on analysis of weight, resistance to abrasion and blasting, Jereh developed optimum wall thickness for swivel joints, introduced advanced equipment and machining technology to ensure the uniformity of wall thickness, the longest service life and highest safety factor with the weight unchanged. Special seal design and seal material significantly increase sealing capability and service life.

Integral Fittings are used for connecting surface manifold. Jereh Integral Fittings are forged from high strength alloy steel, handled by advanced heat treatment technology and conducted strict factory quality control. End connections are union or thread. Many types are available including tees, laterals, wyes, long radius swivels, ells, crosses, adapters and union plugs. We also offer customized design.
