Water Truck Spray Valves, Spray Heads and Spray Bars

Dust suppression is the main job of most water trucks, and the spray system does the work. A well designed spray layout puts water exactly where it is needed on roads, stockpiles and work areas, with even coverage and no wasted water. The valves that control each spray need to open and close cleanly thousands of times a season without leaking or sticking.

T-Rex Manufacturing designs and builds its spray equipment in Australia, and the SV-125 and SV-205 spray valves are found on water carts across the country. Our spray valves are available in pneumatic, hydraulic and electric actuation to suit your control system. Pair them with our heavy duty spray heads for wide, even fan patterns, or fit a complete spray bar or dribble bar kit for rear and side spraying. Keeping valves in service is simple with our insert kits and diaphragms.

From a single replacement valve to a full spray system for a new build, T-Rex can help you lay it out and specify the parts. Browse the spray range below or reach out to our team for advice and a quote.
