Pneumatic Control Valves

Parker 3250 Series flow control valves are designed to accurately meter the flow of air in one direction while allowing free flow in opposite direction. These valves feature fine screw adjustment with a secured sturdy lock nut, allowing precise flow settings for larger diameter cylinders and low-pressure hydraulic service. They are sealed by Buna N / Urethane material for leak-free operation and have brass / cast aluminium body to provide corrosion resistance and tolerance to temperatures up to 180 degrees F. Choose from a wide range of these flow control valves, available in 1/4, 3/8,1/2, 3/4, 1 and 1-1/2 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.

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.

Kingston 305 Series balanced valves are ideal for controlling fluid in high-pressure applications used in automotive and process control equipment. They feature brass construction for structural rigidity and corrosion resistance. These control valves can withstand temperatures up to 200 degrees F and have operating pressures ranging from 1 to 400 PSI.
