The PRO-SOURCE 2556214866PRO is a bi-directional, screw-adjusted air flow control valve designed to regulate airflow in pneumatic systems. The valve features a nickel-plated brass body with a 1/8-inch tube outside diameter and a 1/4-inch male universal thread connection. An integrated adjustment screw allows precise flow rate setting in either direction without requiring additional fittings or adapters. The Buna Nitrile O-ring provides a reliable seal under normal pneumatic operating conditions. This valve is typically installed by pneumatic system technicians or industrial maintenance professionals working on compressed air circuits and automation equipment.
This flow control valve is suited for use in pneumatic control circuits found in light industrial, HVAC automation, and process control applications. The 1/8-inch tube OD sizing fits standard small-bore pneumatic tubing commonly used in actuator lines, valve pilots, and air logic systems. Its bi-directional design eliminates the need to orient the valve for a specific flow direction, simplifying installation in tight or complex plumbing runs.
Designed as an OEM-style replacement or new-installation component for pneumatic control systems using 1/8-inch OD tubing with 1/4-inch male universal thread ports.
Installation is typically performed by qualified pneumatic or HVAC controls technicians. Depressurize the pneumatic circuit completely before removing or installing any flow control valve. Use appropriate thread sealant compatible with compressed air service on all male thread connections. Do not overtighten the adjustment screw, as excessive force can damage the internal needle seat and O-ring.
