Valve Block from a Land Rover. Valves are 12V -ground made by Dunlop. Fittings are toolless press-in ferrules for plain plastic or metal tubing, except inlet which is pipe thread. Pressure switch, 1-way valve, & drier loop. Some include a driver module that steps logical inputs (3-5VDC) up to control outputs (12VDC), but it's not needed for direct-wired controls.

8 lbs (w/o driver module) 8x6x5"
