Water Flow Control Valves

Two-Way Needle & Ball Valves

Pressures from 10,000 to 20,000 PSI

The Needle Valves are standard for on-off service and insure long life on valve seats. They are stainless steel positive gland lock devices require no stem adjustments. These valves are available in two-way straight configurations in sizes to suit most applications. The medium pressure components use a compact coned-and-threaded connection which permits the larger bore sizes and increased flow rates common in this pressure class. The Extreme Service Valve has a tungsten carbide valve and seat and is recommended for use in applications in which the valve will be open the majority of the time.

The Two-Way Ball Valves provide complete shut-off of liquid flow in either direction with just a 1/4 turn even in the most severe applications. They feature blowout-proof stem tips, Teflon Packing below the stem threads, removable seat connections, replaceable PEEK seats, and require no stem adjustments. These valves are available in two-way configurations in sizes to suit most applications. The medium pressure components use a compact coned-and-threaded connection which permits the larger bore sizes and increased flow rates common in this pressure class. Gardner Denver offers a complete line of complementary NPT, medium and high-pressure fittings, tubing, hoses, check valves, line filters, and anti-vibration gland assemblies.
