Pro-source 2556138367PRO Air Flow Control Valve 3/8 in

Product Description

The PRO-SOURCE 2556138367PRO is a meter-out, knob-adjusted pneumatic flow control valve designed to regulate airflow on the exhaust side of a pneumatic actuator or cylinder. Built with a nickel-plated brass body and a Buna Nitrile O-ring, this valve accepts 3/8-inch OD tubing and connects via a 3/8-inch male thread with a universal thread type. It provides smooth, repeatable speed control for pneumatic circuits in industrial, automation, and process-control applications. The knob adjustment allows field technicians to dial in the desired flow rate without additional tooling. Weighing 0.24 pounds, it is compact and straightforward to integrate into existing pneumatic assemblies.

This flow control valve is suited for use in compressed-air systems where precise cylinder or actuator speed control is required. Typical applications include pneumatic conveying systems, automated assembly equipment, and process machinery in manufacturing environments. The meter-out configuration controls the air exhausting from an actuator, which provides smoother motion and better load control compared to meter-in setups. Industrial maintenance technicians and automation system integrators are the primary installers of this type of component.

Key Features

• Meter-out flow control limits exhaust air from actuators for stable, controlled motion
• Knob adjustment allows tool-free flow rate setting in the field
• Nickel-plated brass body resists corrosion in industrial environments
• Buna Nitrile O-ring provides reliable sealing against compressed air
• 3/8-inch OD tube connection with 3/8-inch male universal thread for broad fitment
• Compact and lightweight at 0.24 pounds for easy integration into tight pneumatic panels

Compatibility

Designed as an OEM-style replacement or new-installation flow control valve for pneumatic systems using 3/8-inch OD tubing and 3/8-inch male thread connections with universal thread type.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pneumatic systems specialist. Depressurize and lock out the pneumatic circuit before removing or installing any flow control valves. Verify thread compatibility and apply appropriate thread sealant or tape per system requirements before tightening. After installation, gradually pressurize the system and adjust the knob to the desired flow rate while observing actuator motion for proper operation.
