Easy Read Flow Control, Needle and Check Valves

Deltrol's unique line of Easy Read Flow and Needle Valves incorporate a metal setting knob and stem for added durability and positive operation. Color coding on the stem allows you to precisely set flow requirements by simply turning knob to the appropriate marking.
 
Flow Control Valves provide controlled flow in one direction, free flow in the 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; lull flow is permitted in the direction of the arrow, positive check in the opposite direction.
 
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.
