Pro-source 4827200315PRO Air Flow Control Valve 1/4 in

Product Description

The PRO-SOURCE 4827200315PRO is a tamper-resistant air flow control valve designed to regulate airflow in pneumatic and fluid control systems. Built with a nickel-plated brass body, this valve connects to 1/4 inch outside diameter tubing and features a 1/8 inch male thread fitting. The tamper-resistant design prevents unauthorized or accidental adjustment once set to the desired flow rate. It is suited for HVAC controls, pneumatic instrumentation, and light industrial applications where consistent, controlled flow is required. Licensed trades and maintenance professionals install this type of valve during system commissioning or service calls.

This valve is appropriate for use in residential and light commercial pneumatic control circuits, compressed air lines, and similar low-pressure fluid handling systems. The 1/4 inch tube OD connection is a common size in control-line applications, making this a practical replacement or add-on component in existing pneumatic control networks. Installation typically occurs inline where precise airflow restriction is needed to maintain system balance or protect downstream components.

Key Features

• Tamper-resistant design locks in the set flow rate to prevent accidental or unauthorized adjustment
• Nickel-plated brass body provides corrosion resistance in typical pneumatic and control-line environments
• 1/4 inch tube OD connection suits common pneumatic control tubing
• 1/8 inch male thread allows direct connection to standard ported fittings and manifolds
• Compact form factor at 1.34 inches height and 1.04 inches length for tight installation spaces

Compatibility

Designed as an OEM-style flow control valve for pneumatic and compressed-air control systems using 1/4 inch OD tubing with 1/8 inch male thread ported connections.

Installation Notes

Installation should be performed by a qualified HVAC technician, pipefitter, or instrumentation technician familiar with pneumatic control systems. Depressurize the system completely before removing or installing any inline valve component. Use appropriate thread sealant on the male thread connection in accordance with the fitting manufacturer and applicable codes. Do not overtighten the tube fitting; follow the fitting manufacturer's hand-tight-plus-turns procedure to avoid deforming the tube seat.
