The ball valves are rated as PN 25 and are operated using lockable lever handles.
The sub meter assemblies include ball valves with male thread to swivel nut couplings to suit either nut and tail or ball joint (NSW/ACT) drinking water meters.
The ball valves, including lever handles, are manufactured from dezincification resistant lead-free copper alloy and incorporate a Grade 316 stainless steel ball.
A ball valve range is also available with lilac-coloured handles for non-drinking water applications.
