This appraisal is for DN 20 metal-bodied ball valves for meter assembly applications. This issue 2 is to include additional ball valves with end type connections to suit DN 20 ball joint union meters (NSW/ACT) and also to provide an alternative method of connection to water meter assembly brackets.
The ball valves are rated as PN 16 and are operated using a lockable lever handle.
The end configurations are:
- DN 25 PE compression joint to nut and tail union (swivel nut) for connection to a standard domestic water meter.
- ¾” female thread (with 1” male thread to facilitate connection to a water meter assembly bracket) to 1” nut and tail union (swivel nut) for connection to a standard domestic water meter.
- ¾” female thread (with a grooved spigot and circlip to facilitate connection to a water meter assembly bracket) to nut and tail union (swivel nut) for connection to a standard domestic water meter.
- ¾” female thread (with 1” male thread to facilitate connection to a water meter assembly bracket) to ball joint union (swivel nut) for connection to a NSW/ACT water meter
- ¾” female thread (with a grooved spigot and circlip to facilitate connection to a water meter assembly bracket) to ball joint union (swivel nut) for connection to a NSW/ACT water meter.
The ball valves are manufactured from dezincification resistant copper alloy and incorporate a Grade 316 stainless steel ball.
