Flow Control Valve 1/4 in PTC to 1/4 in NPT

This Legris 7665 56 14 is a miniature flow control regulator for pneumatic circuits. It combines a 1/4 inch push-to-connect inlet with a 1/4 inch male NPT outlet. The valve handles a maximum pressure of 145 psi and operates up to 158 degrees F.

Installers needing directional flow regulation

The 360 degree rotation allows flexible positioning during assembly. It suits systems requiring controlled flow in one direction with a compact footprint. Buyers needing bi-directional control or a different port configuration should look elsewhere.

Maximum pressure rating 145 psi

This single figure defines the safe operating limit for the valve in your pneumatic system. Exceeding 145 psi risks component failure and leaks. Verify your circuit pressure stays within the 14.5 to 145 psi range before specifying this part.

Questions about this item

What tubing size do I need for the 1/4 in push-to-connect inlet on this flow control valve?

Use 1/4 inch outer-diameter pneumatic tubing that is rated for at least 145 psi and 158 °F to match the valve’s inlet specification.

Will the 1/4 in NPT outlet thread directly into my existing 1/4 in NPT fittings?

Yes, the outlet is a standard 1/4 inch male NPT thread, so it screws into any matching 1/4 inch female NPT port without adapters.

How can I verify the valve is regulating flow correctly after installation?

With supply pressure between 14.5 and 145 psi, adjust the 360-degree knob and confirm airflow changes smoothly in the controlled direction while the free-flow direction remains unrestricted.
