The Digga ECV and pile kick back when installing screw piles.

Digga Australia - digga drive unit
Screw piles or helical piles are installed to an engineered torque specification. By the time installation torque is reached and the operator stops the machine, the screw pile has built up rotational energy - similar to a rubber band on a wind up model aeroplane.

This energy that is stored in the anchor needs to be released before the drive unit is disconnected. The ECV bypasses the stored energy allowing the anchor to “unwind” in a controlled manner. Without this valve, the pressure contained when holding the pile in place would be forced up the pile and into the drive unit resulting in potential damage & costly repairs for the motor and gearbox.

See the diagram below, the red arrow demonstrates the force of the energy up the screw pile.


Digga's flow reversal bypass valve (Energy Control Valve - ECV) is fitted as standard to Digga Screw Anchor Drives and can be retro fitted to drilling drives as required.

The Digga ECV effectively protects the motor in your drive from rapid oil decompression and easily converts your auger drive into a dedicated screw anchor drive.

To retro fit the ECV to your auger drive follow the 3 steps below:

Sydney wide DNA Contract Services are a well-established company specialising in excavations, earthworks, haulage and sediment control and trusted by some of Australia’s biggest builders. They were contracted as part of a project with Channel 7’s Better Homes and Gardens to drill piers for a granny flat behind a house in Blacktown, NSW and decided the Digga PD6 Auger Drive unit was the tool for the job. Attached to their 5.5 tonne Hitachi excavator they were never going to have any problems and DNA told us the PD6 drilled through with ease. Alex Vella of DNA Contract Services commented: “I have been using Digga now for 2 years and will continue to do so. DNA have used many other products on the market but find Digga to produce plenty of power at an affordable cost. In my opinion, Digga products give the best bang for buck!”
