Flow Control Valves

mrostop

Parkers 337 Series Flow Control Valves allow metered flow of air in one direction and allow free flow in the reverse direction. The 337 Series valves are manufactured with a fine tapered needle providing precise flow control, even at low flow rates. The perimeter of the adjustment knob features numerical micrometer position markings providing a visual indication of the setting. Once the desired flow is selected, a set screw can be tightened to maintain the setting. These valves are available with NPTF ports in 1/8",1/4", 3/8", 1/2", and 3/4" sizes. This series is recommended for pneumatic service.
