Flow Control Valve - 337 Series
*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.
Parker 337 Series Flow Control Valves efficiently meter flow of air in one direction while allowing free flow in the reverse direction to ensure maximum productivity. The plunger in these valves is a fine tapered needle, which provides 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 flow controls settings. Once the desired flow is selected, a set screw can be tightened to maintain the settings. Due to the light spring on the return check, the 337 flow controls have a 1 to 2 psig cracking pressure. Extended temperature versions up to 300 degrees F are available as specials.
