Pneumatic Control Valves

Parker 337 Series flow control valves regulate the flow of air in one direction while permitting free flow in the reverse direction for maximum productivity. These valves feature fine tapered needle plunger, thereby allowing flow control with great accuracy (even when flow rates are low) and an adjustment knob with numerical micrometer position markings for visual indication of the flow control settings. They are further integrated with a set screw that can be tightened to maintain the settings and are available in 1/8, 1/4, 3/8, 1/2 and 3/4 inch port sizes.

Parker miniature high-speed pneumatic logic control valves are designed to remotely manage the opening & closing of valves, thereby controlling the flow of fluid. They can be easily programmed for performing predetermined timed or machine cycle operations via a sequencer. The push-in fittings provide an easy pneumatic connection. Choose from a wide range of miniature pneumatic control valves, available in sub-base mounted element, step module, pneumatic combinable element, line mounted element, memory relay, normally closed, normally open, sensor relay, amplifier relay and pressure switch variants.
