Does Your Excavator Only Have a Single Flow Hammer Circuit?
Need an Easy & Cost Effective Way to Reverse Your Attachment?

Flow Reversal Valves, for easy two way (Bi-Directional) use of your auger drive or other attachments. Utilising the single way flow from your hammer circuit, forward and reverse control is obtained via an electrical signal either 12 or 24 volt (different models).

The Digga Flow reversal system has been rated to ensure a low pressure drop for the specific valve and drive unit (meaning more power to your drive head). Electrical wiring kits (purchased separately) utilise high quality weather-proof Deutsch connectors for maximum performance and safety on the job site.
