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.

From the closed position, open the valve by turning the metal
knob counter-clockwise until the desired flow volume is
obtained.
The colored band on the stem and the numerical readout
indicate to what extent the valve is opened or closed. Each
color on the color band represents one full turn.
Find the scribe mark on the upper surface of the valve body.
The number on the knob in proximity to the scribe mark will
indicate 10ths of a turn the valve is opened.
Record the information for future reference.
