These Needle Valves are standard for on-off service and insure long life on valve seats. 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. Gardner Denver Water Jetting Systems offers a complete line of complimentary NPT, medium and high pressure fittings, tubing, hoses, check valves, line filters and anti-vibration gland assemblies.
