Over-engineered and built to last these products give you the versatility, peace of mind, and quality you expect from Auger Torque products. A 2-Way Valve is an optional extra on this series of auger drives and enables you to convert a single-acting hammer circuit into the 2-way auxiliary flow. For the auger drives 15000-45 and 18500-45, an optional Pressure Relief Valve is also available. Safeguard your investment by protecting the hydraulic motor from backpressure and hydraulic pressure spikes. High-quality hoses and couplers are standard with this series of auger drives (15000-45 and 18500-45 do not include couplers), type and size need to be specified at the time of purchase.
