Valves
Flowline valves for one-way flow control, reverse-flow prevention, and configured overpressure protection in demanding well-service applications.
Compact reverse-flow protection
Flapper Check Valve
Compact nonreturn valve with an internal flapper that opens with forward flow and closes when flow stops or reverses.
View details
Configured overpressure protection
Pressure Release Valve
Self-resetting overpressure valve that opens at a specified set pressure, relieves through its outlet, and reseats after pressure normalizes.
View details
Automatic nonreturn control
Swing Check Valve
Nonreturn valve with a hinged swing closure that moves with forward flow and seats automatically to block reverse flow.

Quarter-turn flow control
Plug Valve
Manual quarter-turn valve for full-open or closed isolation in treating and pressure-pumping flowlines, offered in 2 x 1, 2 x 2, 3 x 3, and 4 x 4-inch configurations.
View details
Axial reverse-flow protection
Dart Check Valve
Spring-assisted nonreturn valve with an axial dart that opens with forward flow and seats to limit reverse flow.

Fixed-orifice flow restriction
Target Choke Valve
Replaceable-target choke for restricting flow and absorbing erosive energy at a selected fixed orifice size.

What Does the Valve Need to Do?
Choose the valve by the job it must perform. Plug valves provide quarter-turn on/off isolation. Flapper, swing, and dart check valves allow forward flow and close automatically when flow stops or reverses, using different internal closing mechanisms. A pressure release valve opens at its specified set pressure and reseats after the overpressure condition clears. A target choke uses a selected fixed orifice and replaceable target to restrict flow and absorb erosive energy; it is not a positive isolation valve. Flow direction, connections, pressure class, materials, and service requirements must be confirmed for the completed assembly.
