AirTAC 4L21006 3L/4L Push-Pull Mechanical Valve

AirTAC 4L21006 push-pull mechanically operated pneumatic valve from the 3L / 4L line. Manually actuated by a push-pull stem to switch air direction, with 3L as a 3-port (3/2-way) version and 4L as a 4-port (4/2-way) version for controlling single- or double-acting cylinders. Direct-acting construction operates without electrical power, suiting manual control stations, hand-operated fixtures and pneumatic logic circuits. The order code encodes the port size and thread standard.
