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.

Hose Loops are mainly used for transporting fluid in high pressure discharge line, well testing line and cementing slurry line. Jereh Hose Loops include long radius type and flexible type. Long radius type combines long radius swivel joint and integral pup joint, featuring high erosion resistance, less vibration, impact resistance and large flow. Flexible type has single union connection, featuring excellent seal and rotary performance. Jereh Hose Loops are available in both standard service and H₂S service, applicable to cementing, fracturing, acidizing and testing lines. Customized design is also available to meet various demand.

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.

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.
