Hi-Flow™ control valves are single seated, top or cage guided globe valves – probably the simplest, from a construction standpoint, yet most versatile control valve in use. The Hi-Flow™ valve can fit applications with a smaller size valve since the valve has a greater flow capacity than most conventional valves of the same size. Coupled with a high flow capacity, the Hi-Flow™ valve maintains a wide rangeability of 50:1 to ensure precise control.
Heavy duty Hi-Flow™ valves are ruggedly constructed of the highest quality materials, precision machined, and performance tested to assure years of trouble free service. Standard packing consists of PTFE V-rings and wiper to minimize friction without leakage at high operating pressures. Available in brass, iron, or 316 SS body, trim is 316 SS with all welded plug construction to provide superior durability and corrosion resistance.
Our Hi-Flow™ control valves were originally designed and manufactured by Taylor, and are well known as a durable and dependable valve. Dwyer Instruments, Inc. acquired the Hi-Flow™ line in 1991 and has continued manufacturing this great quality valve under the W.E. Anderson division.
