I. Characteristics
2-HA-1 is a two-position three-way directional control valve, featuring one inlet port, one outlet port, and one exhaust port. When combined with a pressure reducing valve, it not only enables switching of air circuits but also allows adjustment of the output pressure by regulating the pressure reducing valve, thereby increasing or decreasing the air pressure. Its pressure adjustment range is from 0 to 1.0 MPa.
The “Anwochi” 2-HA-1 air-control valve is a handle-operated three-way valve mounted on a panel, featuring an NPT 1/4" inlet and working port. It incorporates a spring and a counterbalancing cam that lock the handle in two extreme positions. The 2-HA-1L model with locking mechanism includes an additional external handle latch that must be manually released to prevent accidental operation. The 2-HA-1W reset-type valve, once opened and the external force removed, automatically returns to its original position. This is a lift-type pneumatic directional control valve consisting of a cam housing section and a valve section comprising a three-way valve unit.
