The 337 series flow control valve adjustment knob features a numerical micrometer position for visual indication, and includes a fine taper needle which provides precise flow control even at low flow rates.
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.
