Pro-source 2556114867PRO Air Flow Control Valve 1/8 in

Product Description

The PRO-SOURCE 2556114867PRO is a meter-out knob-adjusted flow control valve designed to regulate compressed air flow in pneumatic systems. It controls airflow on the exhaust side of the circuit, allowing technicians to set actuator speed by restricting outgoing flow while permitting free flow in the supply direction. The body is nickel-plated brass for corrosion resistance in industrial environments. A 1/4-inch male thread connects to standard ports, and the 1/8-inch tube OD push-to-connect fitting accepts small-bore pneumatic tubing. The Buna Nitrile O-ring provides reliable sealing across a broad range of operating conditions. At 0.11 pounds, it is compact and lightweight for tight panel or manifold installations.

This valve is suited for pneumatic automation and motion control applications in manufacturing, maintenance, and industrial facility environments. It is typically installed inline with pneumatic cylinders, actuators, or directional control valves where speed control of the extending or retracting stroke is required. The knob adjustment allows field technicians to fine-tune flow without tools, making it practical for quick commissioning or maintenance adjustments on the shop floor or in the field.

Key Features

• Meter-out design controls exhaust airflow for consistent actuator speed
• Knob adjustment allows tool-free flow rate tuning in the field
• Nickel-plated brass body offers corrosion resistance in industrial environments
• 1/8-inch tube OD push-to-connect fitting for small-bore pneumatic tubing
• 1/4-inch male thread with universal thread type for broad port compatibility
• Buna Nitrile O-ring provides durable sealing across typical pneumatic operating conditions

Compatibility

Designed as an OEM-style replacement or direct-fit component for pneumatic circuits using 1/8-inch OD tubing and 1/4-inch male-threaded ports in standard industrial pneumatic systems.

Installation Notes

Installation is typically performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize the pneumatic circuit completely before removing or installing any flow control valve. Verify thread type and tube OD match the existing circuit before assembly to avoid leaks or fitting damage. Apply appropriate thread sealant or tape per system requirements and confirm all push-to-connect tubing is fully seated before repressurizing the system.
