Description

Intended for equipment that operates under repeated load, vibration and contamination exposure, the Overcenter Valve (OEM 8231 1203 78) supports the feed and drill-carriage mechanism. By managing pressure or flow at the required point in the circuit, it helps the machine maintain predictable hydraulic response during operation.

Controlled internal clearances, sealing surfaces and flow passages are important for predictable response and reduced internal leakage across repeated pressure cycles. The part supports cost-conscious maintenance strategies that require a reliable cross-reference option for professional drilling equipment. Typical listed applications include FLEXIROC D60SF and FLEXIROC D65 – 10 LF, subject to machine specification and configuration verification.

Supported by Delkom’s experience in alternative rock-drill and drill-rig spare parts, this component is supplied for professional mining and tunneling maintenance worldwide. For availability, pricing and an application check, quote Delkom reference 120 400 053 and OEM reference 8231 1203 78.
