What is a Solenoid?
A solenoid, also known as a solenoid valve, or air valve, is the device that controls the flow of air on electronic kits.
They comes in varying sizes, which offer varying speeds. The nicest looking ones come on a manifold for easy compact fitting such as this RidePro item:-
Our basic kits have quite small (as you can see by coke can) but incredibly reliable solenoids. In January 2009 I stripped a set for a customer because they were not seating correctly. They had been on the car since 2003 with no maintenance, and the tank had never been drained. I stripped them, cleaned them and reassembled them and they are as good as new. This is not the case for cheap copies.
These are not only incredibly well made, very reliable, and nice looking with the red anodised finish, but also easy to fit as all ports have the function etched into them.
Basic solenoids are called RidePro, and larger versions are Big Red. These are the largest recommended for daily use. We can supply bigger ones which do increase speed, but they are harder to control as they allow too much air through and its hard to set them to the desired height – of course for speed they are the ultimate.
RidePro and BigRed solenoids are etches with the port names so there is no confusion. You need two solenoids for each bag – up and down.
Large valves are modular and can be bolted together to make a single manifold, with one or two supplies, or separate and located near each wheel for increased speed.
We do not recommend and will not fit single circuit systems, where one set of solenoids controls two air bags as these are dangerous.
