DART TYPE CHECK VALVES

ACT DART TYPE CHECK VALVES are widely used in well stimulation operation. IT has a spring operated Dart Check which eliminates back flow during operations. ACT manufactures this valve for pressure rating up to 15,000 PSI. Sizes available are 1.1/2, 2 & 3. Periodical maintenance of Valves in service enhances durability. ACT dart style check valves are available in 1 through 3 sizes in standard and sour gas services models.

TWO WAY CHECK VALVE

TWO WAY CHECK VALVE

Two way Check Valve may be landed in the tubing hanger. These are available up to 20,000 PSI in materials to resist sulfide stress cracking and other hostile environment encountered in oil and gas production. The ACT special shallow threads on type ‘H’ Back Pressure Valves and plugs provide strength for extreme pressures and long service life with minimum reduction in bore through the threaded portion of the tubing hanger.

ACT tubing hangers threaded for type ‘H’ valves will pass API drift for the size of tubing suspended. Removal or Installation of type ‘H’ valves through installed tree assemblies may be accomplished quickly and safely against full well pressure eliminating the need for downhole plugs or killing the well.
