Series SV Solenoid Valve will electrically operate pneumatic actuators for on-off applications. When the solenoid valve receives the electrical input signal it switches the pneumatic supply pressure to the actuator, which moves the valve from the closed to open position. The next impulse to the solenoid valve will make the valve move back to the closed position. The low cost solenoid valve directly mounts onto pneumatic actuators with standard NAMUR mounting configuration eliminating external tubing and fittings. Buna-N o-rings are included to seal the valve ports to the side of the actuator. Standard features include a manual override, safety position by mechanical spring, and a NEMA 4X enclosure. Direct mounts onto D, S, J, F, C, DA, or SR actuators.
