T-Rex VAS-80RG 80 mm 3 inch diaphragm shut-off valve
80 mm (3 inch) roll groove ports
Applications:
- medium flow applications
- side batter sprays
- road washing sprays
- pressurised dribble bars
Valve operation:
- operates opposite to a butterfly valve due to the use of a convex diaphragm
- air pressure maintains this valve in a closed position
- removing the air pressure and applying at least 1.4 bar (20 psi) of water pressure will lift the diaphragm allowing water to flow
- the convex diaphragm will maintain the valve in a closed position even when there is no air pressure present
- this feature will stop water from leaking through the valve when the truck is off, and air pressure is lost

The T-Rex story
Who are we?
We're a multi-generational Australian family business that was founded in 1985 by Rex Jones. 
Rex has always focused on producing products for harsh environments in the demolition and earthmoving industries. 
Over time we found our niche in water trucks, and this is where we plan to stay.
What do we do?
We innovate. 
We see problems and make solutions. 
We have a fully equipped manufacturing facility with the ability to make just about anything from steel. 
We also work with great local companies who support us with CNC machining, powder coating and laser cutting. 
All our designs are made in house using the latest 3d cad software.
We don't build water trucks, just the components so you can create the best.
We're here to support the water truck industry with our products. 
We work with some of the most respected water truck manufactures in Australia.
What do we stand for?
We understand the demands of the industry and your customers.
