ELECTRIC VALVES

ELECTRIC VALVES
SMC has provided two double solenoid valves. If you pulse one of the solenoids to make the cylinder extend, you must then pulse the opposite solenoid to make it retract. Either solenoid may be left in the energized state. This is a great valve to use to maintain position when the power is turned off at the end of the match. If you use a single solenoid valve and the power is turned off, the valve would shift back to its original position and the cylinder will retract. A double solenoid valve will maintain its position until you turn on the opposite solenoid. The orange buttons on the top of the valves are manual overrides. With a double solenoid valve you can depress the override and the valve will shift and stay in that position. The valve is pilot operated and requires a minimum pressure of 20 psi to work. The valve comes separate from the mounting block and must be assembled to it. There are 2 gaskets included. Use the one with holes for the mounting screws. Always avoid turning on both solenoids at the same time. While this won’t hurt the valve, you cannot be sure which way the spool will shift. There is also a 24vdc double solenoid valve included in the kit as a spare. Should you need to replace one of the 12V solenoid valves, just unscrew the 24V pilot valves from each end of the spare and swap the solenoid bodies. Remount the 12vdc pilot valves. Then remount the solenoid assembly back onto the sub base-mounting block.
