6A Valves including gate valve, plug valve, ball valve, multiple valve, actuated shutoff and check valves may be used for well control, flowline control, re-pressuring and cycling service. It may be operated with a handwheel or a wrench- (or bar-) operated mechanism or with a handwheel-actuated gear mechanism or with a hydraulic, pneumatic and electric-powered actuator.
Multiple valves are full-bore, gate or plug valves, a composite arrangement of valves. They are used in dual, triple, quadruple and quintuple parallel-string completions for production well control, re-pressuring and cycling service. Multiple valves have the conduits of the several bores terminating in, and integral with or permanently attached to, single connectors at each end. The end-connector size is determined by the nominal size of the tubing head or tubing-head adapter to which the lowermost tree valve is being attached.
Actuated valves are provided with an actuator to automatically open or close the valve. They can be flanged, threaded, or other end-connected, full-bore or reduced-opening, gate valves or plug type valves. The actuators may be Hydraulic, pneumatic and electric-powered actuators. The upper limit of the rated temperature range for hydraulic and pneumatic actuators is at least 65° C (150° F). The upper limit of the rated temperature range for retained fluid-powered actuators is at least the upper-limit temperature rating of the mating equipment. Each actuator is subjected to a functional test to demonstrate proper assembly and operation. Valves prepared for actuators, including multiple, prepared for actuators include all parts required to properly function when assembled with the actuator.
Check valves are of the swing and lift check types. The valves may be full-opening or reduced-opening and are used to permit fluid flow in only one direction. All full-opening valves have round passageways through the body and seats. Regular-lift and swing check valves are customarily made with reduced bores through the seat and are sized at the option of the manufacturer.
Positive and adjustable chokes are chokes that include restrictions or orifices to control the flow rate of fluids. Chokes are not intended to be used as shutoff valves. Adjustable chokes have an externally controlled variable-area orifice coupled with an orifice-area-indicating mechanism. Adjustable chokes may be operated by manual or actuator. Adjustable chokes are equipped with a visible orifice-area-indicating mechanism to define the orifice area at any adjusted choke setting throughout its operating range. Positive chokes accommodate replaceable parts having fixed orifice dimensions, which are commonly called flow beans. Special corrosion- and abrasion-resistant materials, coatings or overlays shall be used for adjustable-choke stem tips and positive-choke flow beans
