Peter Paul valve, #74
The Peter Paul valve, #74 valve is normally open. This electric over air solenoid valve operates on 12V direct current. The main valve body is stainless steel. Use the #74 valve to dump the standard airbags on your trailer suspension when you mount a lift kit. Use both the #74 and the #73, HW73PP9ZGM, which defaults normally closed to operate a lift kit. The #74 Peter Paul valve shortens your turning radius by allowing you to dump the rear/front axle, making tight turns with a spread much more efficient. Both the #73 and #74 use only two wires, one ground and one hot; however, you will be pleased to know that as long as both wires are hooked up, which way they are wired does NOT matter.
