The Self Adjusting ‘SA’ valve wheel drive plate is designed to suit flat valve wheels with varying numbers of spokes. There are five versions as folows:
- VAS-SA003 – for smaller wheels with 3 or 6 spokes
- VAS-SA004 – for valve wheels with 4 or 8 spokes
- VAS-SA005 – for valve wheels with 5 spokes
- VAS-SA006 – for larger wheels with 6 spokes
- VAS-SA007 – for valve wheels with 7 spokes
The patented design with spring-loaded spoke drive dogs means that the drive plate will automatically self-centralise on the wheel as soon as drive rotation commences. Avoiding eccentric rotation ensures easy and comfortable holding for the operator.
