Pro-source 2556138166PRO Meter Out Flow Control Valve

Product Description

The PRO-SOURCE 2556138166PRO is a meter-out screw-adjusted flow control valve designed to regulate airflow on the exhaust side of a pneumatic actuator or cylinder. The valve body is constructed from nickel-plated brass, which provides corrosion resistance in compressed-air service environments. It accepts 3/8-inch OD tubing and connects via a 1/4-inch male thread. The Buna Nitrile O-ring provides a reliable seal across a wide range of service temperatures typical in industrial pneumatic systems. This valve is installed by pneumatic system technicians, maintenance mechanics, and fluid power specialists working on automation, tooling, or process control equipment.

This meter-out flow control valve is suited for use in pneumatic circuits where controlled actuator speed on the return or exhaust stroke is required. Typical applications include linear actuators, pneumatic cylinders, and directional control valve assemblies in light industrial and automated manufacturing environments. The screw-adjustment mechanism allows for precise, repeatable flow setting without requiring additional tooling once the valve is installed in line.

Key Features

• Meter-out configuration controls airflow on the exhaust side for smooth actuator speed regulation
• Screw-adjusted flow control allows repeatable, tool-free tuning after installation
• Nickel-plated brass body resists corrosion in standard compressed-air service
• Buna Nitrile O-ring sealing material compatible with standard pneumatic service conditions
• 3/8-inch OD tube fitting with universal thread type for broad system compatibility
• 1/4-inch male thread connection for direct integration into standard pneumatic manifolds and fittings

Compatibility

Designed as an OEM-style replacement or drop-in addition for pneumatic systems using 3/8-inch OD tubing and 1/4-inch male threaded ports in light industrial and automated process applications.

Installation Notes

Installation should be performed by a qualified pneumatic technician or maintenance mechanic. Depressurize and lock out the pneumatic circuit before removing or installing any flow control valves. Apply appropriate thread sealant to male threads per the system manufacturer's recommendation, and avoid overtightening into manifold ports to prevent thread damage in aluminum bodies. After installation, gradually open the screw adjustment and verify actuator speed under controlled conditions before returning the system to full operation.
