Rexroth 2-BA-1 Pilotair® Single Unit Valves, 3-Way Button Operated
Aventics "A" Pilotair® Panel Mounted Valves (3-Way, 4-Way & Multi-Function)
The model 2-BA-1 PILOTAIR Valve is a panel mounted, 2 position button operated 3-way valve with 1/4" NPT inlet and outlet ports.
The Panel-Mounted "A" PILOTAIR Valve is a poppet-type pneumatic directional control valve consisting of a cam housing portion and a valve portion containing from one to four 3-way valve units.
The "A" PILOTAIR Valves’ streamlined compact design makes them especially suited for deluxe panel mountings such as in consoles or control panels. They can be mounted in either horizontal or vertical panels. The internal parts are enclosed to make them ideal for outdoors installations or other unfavorable working conditions.
Operating Versatility
Versatility has been designed into the operating cams. By reversing, rotating and rearranging these all-purpose cams, all the listed combinations can be made with a minimum of parts. Single unit valves for 3-way operation may be normally open or normally closed. The two unit valves have two, three, or five positions of operation as do the three and four unit valves. (See operation.) Detents can be had for two, three or five positions, or handle may be spring returned to center for three position operation.
Operation
In release position, as shown, the valve disc seats on the inlet valve seat and seals the passage from the inlet to the outlet port. The outlet port is vented to atmosphere through the center of the plunger.
As the plunger is forced downward by the cam force it seats on the valve disc. This seals the passage between the outlet port and atmosphere.
Further downward travel of the plunger unseats the valve disc from the inlet valve seat and allows inlet air pressure to flow to the outlet port.
