Watts FluidAir R216-02F Precision Pressure Regulator (Part No. 162146)

Description:

The Watts FluidAir R216-02F Precision Pressure Regulator (Part No. 162146) is a 1/4 inch NPT pneumatic regulator designed to provide accurate low-pressure control in compressed air systems. It features a reduced pressure adjustment range of 0–20 PSI and a diaphragm-operated design with a large sensing area for fast, precise regulation. The regulator is commonly installed in instrumentation systems, laboratory equipment, pneumatic control panels, manufacturing machinery, and automation applications requiring stable low-pressure air control.

Applications:

The Watts FluidAir R216-02F is widely used in industrial automation, process control systems, pneumatic instrumentation, testing equipment, OEM machinery, assembly lines, and compressed air distribution systems where precise low-pressure regulation is critical. Its high-flow performance and rugged construction make it suitable for applications with varying flow demands while maintaining consistent downstream pressure to protect sensitive pneumatic components and improve system reliability.
