Power valve series VEX includes a regulator valve (VEX1*0), precision regulator (VEX1*3), 3 position valve (VEX3) and a economy valve (VEX5). The 3 port large capacity poppet exhausting regulator is equipped with a relief port the same size as the connection port. The 3-port, 3-position double solenoid that permits vacuum suction, vacuum destruction, & suspension (closed) is ideal for a system

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.
