Hi-Flow™ Control Valves are versatile, single-seated, top-guided globe valves designed for precise control of pressure, temperature, level and flow process variables at an economical price. Standard models incorporate push-to-close action and linear flow characteristics generally accepted as industry standard; however, control valves with push-to-open action and/or equal percentage flow characteristics are also readily available to satisfy unique process control applications. High flow capacity coupled with superior rangeability (50:1) inherent on the Hi-Flow™ control valve design enables the selection of standard models for a wide variety of process control applications without sacrificing control precision. Restricted trim and needle valves are also readily available for extreme low-flow applications with no reduction in pipe size required.

Heavy-duty Hi-Flow™ Control Valves are ruggedly constructed of the highest quality materials, precision machined and performance tested to assure years of trouble-free service. Available with bronze or 316SS body, trim is 316SS with all welded plug construction to provide superior durability and corrosion resistance. Standard packing consists of spring loaded PTFE V-rings (3) and wiper to minimize friction without leakage at high operating pressures. Inverted V-ring construction for vacuum service; double opposing V-ring construction for alternating positive pressure/vacuum service; and graphite packing with or without built in lubricator are also readily available.
