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. Accommodate metric tubing O.D ranging from 6 mm to 12 mm, inch tube ranging from 1/4" to 1/2", thread sizes range is from R, PT, BSPT 1/8 to R, PT, BSPT 1/2..
