I. Characteristics
The 2-HA-2 air-control valve is a 2-, 3-, or 5-port valve installed on a panel, featuring one inlet and two outlets. It offers a locking mechanism at the handle position—a manually released locking handle, designated as the 2-HA-2L model with a latch, to prevent accidental operation—or a spring-return-to-center mechanism, designated as the 2-HA-2Z reset model. All ports are NPT 1/4".
The 2-HA-2 air-control valve is a lift-type pneumatic directional control valve consisting of a cam housing section and a valve section that contains one to four three-way valve units.
