2-HA-3 and 2-HA-4 are extensions of 2-HA-2. They were created to furnish a housing that will operate up to four 3-way valves to provide a variety of functions. The body assembly of the 2-HA-3 and 2-HA-4 is made up of two 2-HA-2 bodies under a single housing. The supply port of each body requires a separate supply source. 2-HA-3 has one cavity plugged to provide a three unit assembly, usually cavity 1L. It is possible to operate all four valves with a single handle or in any combination from one to three valves with the left hand handle or with the right hand handle. Double handle assemblies are provided for space conservation and for applications requiring two handles located adjacent to each other. Thus, two different functions can be controlled. As an example, the left handle can control direction (forward or reverse) and the right handle, range (1st, 2nd, 3rd and 4th gear).
