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 1/8" threads are the port used to control a throttle, intake unloaders or discharge valve. Also equipped with manual unloader / control lever which is located at the top of the valve. The bottom one, which is larger than the top one, controls the valve itself and should not be adjusted.
