is the only manufacturer of the 3-Dump Manifold. We suggest using this manifold
in pairs with a twin pump setup. Similar to the 5 dump manifold, this system
works off vehicle weight. The concept is simple: 1 dump valve for each corner,
and 1 valve that returns the fluid back to the pump reservoir. When you
want to lift the front left, the front right valve is activated allowing
fluid to rush in, and since the valve is open the fluid cannot build pressure
in that areas and rushes to fill all non-open areas thus in this case lifting
the front left. The same technique is applied to the rear dump manifold.
When lowering the car, the pressurized valves PLUS the 3th return valve
is activated. This set-up also provides a clean look opposed to typical
4 dump setup with an array of fittings. 12 prong switches must be used for
main switch wiring, 6 prongs to be used for desired corner switches. A single
3 dump manifold can also be used on a 1 pump front/back only configuration.
System capabilities: This setup will allow all (up/down) front (up/down), back (up/down), sides (up/down), and any corner(s) to be lifted from a pancaked position (corners require individual 6-prong switches). Furthermore, it allows individual slow-down control of the front and pack when dropping the vehicle.
Important note: As the manifold works on weight of the vehicle, pancakes up or down speed/priority corner are determined by unbalanced weight)

Our manifolds use only genuine Delta dump stems and coils supplied with 24” wire leads. Don’t be confused with Delta knockoffs, these have been proven to be some of the most reliable dumps available.
Each 3 dump manifold body is CNC machined with a brushed aluminum finish. A 3/8" NPT ‘return' port is supplied in the front center of the manifold, while the ‘press' can be supplied through one of the (3) 3/8" NPT ports available (one on each side, or front next to the ‘return'). One row of (2) 3/8" NPT cylinder outlet ports is supplied on the top of the manifold and one row on the bottom. In the event that accumulators are used, they may be mounted to the bottom row, while the lines out to the cylinders may be fed off the top (or vice versa).
note: Only ONE ‘press’ port can be used, the other
two must be capped with the supplied allen plugs. All ports not being
used must be plugged!
To mount the manifold we suggest using the (2) 3/16 supplied mounting holes supported by a rack (not supplied by Hydroholics)
