Miniature Preset Flow Control Valves

Flow Controls For Pneumatic Air Systems

Miniature Preset Flow Controls maintain a constant flow in one direction and full flow in the opposite direction. Universal Power Conversion offers quick turnaround times on our extensive selection of miniature preset flow controls for gas or pressurized air applications. Flow controls can be selected below based on orifice size, with flow controls available in quantities of 5. As an SBA 8(a) certified Orifice Restrictor supplier, we are dedicated to finding the components required for your pneumatic system.

Miniature Preset Flow Control Operation

The operation of the Flow Control is based on the movement of a small disc, which shifts within the housing as the pressure differential changes from forward to reverse. An orifice restrictor is encased in the center of the disc, and a flat surface on one side of the disc seals and permits flow through the orifice. Flow control valves do not require a power source as the air pressure is enough to close the valve. The more the valve closes, the more downstream pressure is reduced.

The amount of flow permitted in the forward direction is full flow. The amount of flow permitted in the reverse direction, which is the sealing side, is determined by the orifice size.

Preset Control Valve Features

UPC preset flow controls offer a number of advantages when properly installed in a compressed air system. Preset flow controls feature a polysulfone orifice for improved durability and longevity in repeated pneumatic applications. Features of preset flow controls include:
  • Precision Molded Orifice
  • Miniature Size
  • Minimum Cracking Pressure
  • Low Cost
