Hand Valves, Shut-off Valves

Hand valves, shut-off valves are used for turning air pressure on and off for pneumatic devices. The three-directional control hand valve, when closed, discharges the residual pressure from the output side (device). Therefore it assures safety at adjustment or repair of the connected devices. The two-directional control hand valve does not have air discharge mechanism, is suited for air supply to a tank or other devices from which the residual pressure should not be discharged. The two-directional control hand valve is also suited for the system where vacuum piping is used. Accommodate metric tubing O.D ranging from 6 mm to 12 mm, inch tube ranging from 1/8″ to 1/2″; thread sizes range is from R, PT, BSPT 1/8 to R, PT, BSPT 1/2.
