Float Valve

Alderdice Ald-Clear Float Valve can be fitted to any shape trough. 

When the water level drops in a trough the float will drop allowing water to fill the trough.  The Ald-Clear Valve is suitable for gravity feed and pressure systems.

Ald-Clear Float Valve


Alderdice Ald-Clear Float Valves are made of Gunmetal Bronze. They have a flap type valve minimizing the chance of the valve blocking.

The 3/4", 1", and 1 1/4" sizes have an Acetal (plastic) replaceable seat fitted as standard. This is to combat any corrosion of the seat due to highly aggressive water at high pressure.

For chain, use only Alderdice Stainless Steel Chain.

Supplied with either a plastic float or a polystyrene float. Also available in either low or high pressure.
