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

DC coil Caution (For VEX3121, VEX3221, VEX3321, and VEX3421) With non-polar type solenoid valves, at times of sudden interruption of the loading power supply, such as emergency shutdown, surge voltage intrusion may be generated from loading equipment with a large capacity (power consumption), and the solenoid valve in a deenergized state may switch over (see Figure 1).
