Duncan Pneumatic Control
Hydraulic flow control valve searches often cover several different circuit functions. IHPC supplies Duncan flow-control products for pneumatic applications and can help identify whether you need one-way, in-line or pressure-compensated control.

A flow control valve regulates the rate at which fluid or compressed air moves through a circuit. The correct configuration depends on whether control is required in one direction or both, where the valve will be mounted, and how consistent the flow must remain as conditions change.
If your requirement is specifically hydraulic, provide the medium and pressure. The current Duncan product shown here is listed within the pneumatic accessories range.
Selection note: Do not substitute a hydraulic control valve or proportional valve without checking the circuit function and manufacturer data.
The catalogue product can be evaluated for several common control requirements. IHPC will confirm the exact available configuration.
Open the Duncan product page to review the currently listed flow-control range.
Ask IHPC to confirm whether directional metering is available for your circuit.
Share port size, mounting position, pressure and target flow for product matching.
Flow control changes actuator speed by restricting the flow rate through a selected path. In pneumatic circuits, the valve position and direction of restriction influence how smoothly a cylinder or actuator moves.
A stable result requires the correct valve type, port size, orientation and adjustment range for the circuit.
Confirm whether the circuit is pneumatic or hydraulic.
Decide whether one-way or two-way control is required.
Identify in-line, port-mounted or manifold placement.
Share pressure, flow and response requirements.
Final suitability depends on the complete application and the current manufacturer technical data.
Metering airflow to tune pneumatic cylinder movement.
Adjustable flow in repetitive industrial sequences.
Controlled extension or return where the circuit permits.
Fine adjustment during commissioning and troubleshooting.
It regulates flow rate so a circuit can control speed or process flow. The correct method depends on the medium and circuit design.
The current Duncan catalogue item is listed under pneumatic accessories. For a hydraulic application, send IHPC the fluid, pressure and circuit details for the correct product route.
It controls flow in one direction while allowing freer flow in the reverse direction. Suitability depends on the circuit arrangement.
It may be considered when flow must remain more consistent as pressure changes. Final selection requires verified manufacturer data.
Send your application details to IHPC for product matching, current availability and a quotation.
