Pilot Valve

Brand Ayush Brass unloader pilot valve, made in the India. 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 100-125 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 purchase 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 Tite, 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.
