Hand valves, shut off valves are designed to turn on and off the airflow, this thread to thread hand valve connects two female threaded ports on both end. Hand valve should only be connected according to the arrow on the body. In the open position air flows from input to output for both two way directional hand valve and three way directional hand valve. In closed position the input air flow is blocked completely for two way directional hand valve, and air downstream from three way directional hand valve will be exhausted to atmosphere. Thread sizes range is from R, PT, BSPT 1/8 to R, PT, BSPT 1/2.

To open the hand valve, shut off valve, turn the cap lever 90 degrees in the clockwise direction until it stops.

To close the hand valve, shut off valve, turn the cap lever 90 degrees in the counterclockwise direction until it stops. As for three-directional control hand valve, the residual pressure in outlet side is released from the gap between cap lever and body just after closing the valve
