Neeco Industries’ flagship API-6A Gate Valve is our Neeco Frac Series 937 Gate Valve. 937 Series Large-bore valves are best suited for the harsh conditions inherent during hydraulic fracturing. 937 Series Valves consist of the NF-700, which is a 7 1/16” full-bore valve. Available in 10,000 to 15,000 PSI pressure ratings and feature a one-piece seat design with simplified parts for easy assembly and operation. It has a proven track record in the field with some of the most well-known service companies operating in the various shale plays of the United States. 937 Series Valves are made with dual-bonnets (lower balancing stem) and contain a ball-screw assembly to reduce torque levels during working pressure. The ball-screw assemblies allow to be open or closed with the least amount of turns while under pressure. Valves are also available with Double-Acting Hydraulic Actuators.
