Pro-source 4827200815PRO Air Flow Control Valve 3/8 in

Product Description

The PRO-SOURCE 4827200815PRO is a tamper-resistant air flow control valve designed to regulate airflow in pneumatic and fluid control systems. Built from nickel-plated brass, this valve offers corrosion resistance and durability in demanding service environments. It accepts a 3/8-inch tube outside diameter and features a 1/4-inch male thread connection. The compact body measures 1.42 inches in length, 1.81 inches in height, and 0.75 inches in width, making it suitable for installations where space is limited. Licensed HVAC technicians and plumbers commonly specify flow control valves like this for precision flow management in compressed air lines, pneumatic controls, and related plumbing assemblies.

This valve is intended for use in residential and light commercial applications requiring controlled, regulated airflow. Its tamper-resistant design is well suited for installations where unauthorized adjustment must be prevented, such as in pneumatic control panels, air-operated equipment, or building automation systems. The 1/4-inch male thread outlet simplifies integration with standard fittings and manifolds common in HVAC and plumbing service work.

Key Features

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber familiar with pneumatic or compressed-air systems. Depressurize the system completely and shut off the air supply before removing or installing any flow control valve. Use appropriate thread sealant or PTFE tape on male threads per manufacturer and local code requirements. Verify tube connections are fully seated and secure before restoring system pressure.
