Description

Deltrol’s unique line of Easy Read Flow Control Valves incorporate a metal setting knob and stem for added durability and positive operation. Color coding on stem allows you to precisely set flow requirements by simply turning the knob to the appropriate marking.

Flow control valves provide flow control 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.

These tough valves are ideal for general industrial and mobile applications including plastic injection molding machines, packaging equipment, machine tools, car washes, hospital beds, and many types of automotive equipment.

Features and Benefits
  • 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 (one full turn per color)
  • Set Screw in knob to maintain flow setting
