External Pilot Piping VVEX2-2 VVEX4-2 Caution When ordering the valve for manifold, be sure to indicate for manifold in case of VEX3422 (internal pilot solenoid) VEX How to Order Manifold Base AN 02 VVEX 2 1 6 AMC Note) Air operated VEX 3220 and VEX3420 (air operated) are used. Distinction between the pilots (internal or external pilot) of the manifold base does not matter.
