Metal Setting Knob and Stem Color Coding and Numerical Readout Allow Positive Setting for Precise Flow Control and Repeatability Can Be Accurately Adjusted Within a Small Fraction of a Turn Available in Six Sizes: 1/8", 1/4", 3/8", 1/2", 3/4" and 1" Flow Control Valves provide controlled flow in one direction, free flow in opposite direction. Flow adjustment can be made under pressure. Setting knob can be locked in any desired position with convenient set screw. Easy Read Check Valves operate on slight differential pressure; full flow is permitted in the direction of the arrow, positive check in the opposite direction.
