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
