Air Compressor Unloader Control Pilot Valve 145-175 PSI Brass New
Brand new air compressor unloader pilot valve, made in the USA. The valve is used to operate a compressed air system at a constant run with a preset pressure operating range to actuate throttle controls, intake unloaders, or air-actuated discharge valves. The valves preset operating range is 145-175 PSI, it has 1/4" male NPT threads that would be used for air hook-up or screwed into the compressor tank and has 1/8" female NPT threads on the side of the valve (as shown in the picture). The 1/8" threads are the port used to control a throttle, intake unloaders, or discharge valve. If more than one outlet is needed it is common to use a "tee" to make multiple ports which can be purchased at a local hardware store.
This valve's preset pressure can be adjusted, below the manual unloader lever on the top of the valve, there are two screw settings that can be adjusted. The bottom one, which is larger than the top one, controls the valve itself DO NOT ADJUST THE BOTTOM. The top one, which is the smaller one, right below the manual lift lever, controls the pressure setting, when screwed in it will INCREASE both cut-in and cut-out pressure and when screwed out it will DECREASE both cut-in and cut-out pressure, it is not recommended to be adjusted more than about 15 PSI in either direction.
