What Farmco Recommends It For:
The RDG Raindrop high pressure float valve is our pick for livestock troughs and tanks connected to mains water or pumped supply lines. It handles up to 140ft of head (60psi), making it ideal for bore pumps, pressure systems and long poly runs. If your stock water comes in under real pressure, this valve keeps it under control.
Why It’s a Farmco Favourite:
Australian farmers have relied on this valve for over 30 years. Its tough glass filled nylon body stands up to harsh sun, hard water and constant pressure. It comes complete with stem, bullet and pin, so you can fit it straight out of the box.
Why Choose This High Pressure Float Valve?
RDG Corporation builds the Raindrop float valve from glass filled nylon, a material that resists corrosion and holds its strength through scorching summers and frosty winter mornings. The solid body copes with knocks from thirsty cattle and sheep, and it won’t rust like older metal valves.
Built to Handle Mains and Pumped Supply
This 1¼” (32mm) high pressure float valve is rated to 140ft of head (60psi). Depending on the rod length and float size, the Raindrop range can handle pressures up to 90psi (700kPa). The large inlet delivers strong flow, so troughs refill fast when stock drink heavily in hot weather. As the water rises, the float lifts the arm and shuts the valve off firmly, so you won’t waste water through overflow.
Easy Install, Simple Maintenance
Screw the valve onto your trough inlet, attach your float, and set the arm to your preferred water level. The adjustment bolt lets you fine-tune the shut-off point, and the simple design makes servicing quick in the paddock.
