The motorised valves are available as single or double acting and incorporate a suck back device to eliminate nozzle dripping when the master dump valve is closed. The valves are available in three or five section versions and further section valves can be added if required. An in cab switch box that includes pressure regulation and wiring loom is included. Maximum pressure rating is 20 bar (300 psi) and a flow rate of 150 litres per minute
