RolAir 131B2 OEM Pilot Unloader Valve, Dual Control, 105-125psi

The RolAir 131B2 is a durable, factory-grade pilot valve designed for dual control air compressor systems, giving users the flexibility to operate in either start/stop or continuous run mode.

Built for precision and reliability, this valve automatically controls the compressor's discharge pressure by opening or closing based on preset cut-in and cut-out pressures. When operating in continuous mode, it engages the unloader valve to prevent overpressurization while keeping the motor running.

This pilot valve is commonly found on RolAir compressors and other brands with similar unloader-style systems. It comes equipped with a throttle control port and unloader valve port, allowing integration with gas-powered compressors or electric models using unloader valves. The adjustable pressure settings make it versatile for a wide range of compressor applications.

The RolAir 131B2 pilot unloader valve is pre-set to load at 105psi and unload at 125psi. This valve will blow off pressure at the top end setpoint and is designed to be used with air compressors that do not have built in head unloaders.
