Buyers Products Company F400S 1/4 Inch NPT Steel Flow Control Valve

Hydraulic Flow Control Valve

The Buyers Products F400S is a hydraulic flow control valve built for industrial plumbing systems. It regulates fluid movement in hydraulic circuits with a carbon steel body rated for demanding environments. The valve uses 1/4 inch NPT connections on both inlet and outlet ports for standard pipe threading. It suits technicians and engineers managing hydraulic power units or mobile equipment.

One-Way Control Upgrade

This valve replaces basic shut-off or unregulated fittings where precise, one-way flow metering is required. The jump is worth it when a circuit demands repeatable flow adjustment up to 5 gpm and pressure tolerance up to 5,000 psi. Its carbon steel construction resists deformation under high-pressure cycling better than brass or aluminium alternatives. Install it where flow must be set once and held without reverse passage.

High-Pressure Hydraulic Circuits

The F400S suits hydraulic systems needing reliable, one-way flow regulation at up to 5,000 psi. It fits applications such as loader valves, cylinder speed control and test stands using 1/4 inch NPT plumbing. Builders needing bi-directional control, electronic actuation or larger port sizes should look at other valve types. Systems requiring lower pressure ratings or different thread standards will not match this specification.
