Control Valve

Built for demanding maintenance cycles on mining and tunneling equipment, the Control Valve (OEM 850 985 79) is a dependable aftermarket spare part for the percussion and drifter assembly. The component regulates a defined part of the fluid circuit, supporting controlled actuator movement and protection of connected hydraulic elements.

The part supports cost-conscious maintenance strategies that require a reliable cross-reference option for professional drilling equipment. Precision at the spool, seat or cartridge interface helps preserve hydraulic response and consistent switching as operating pressure changes. Because machine configurations can vary by model, year and serial range, confirm the OEM reference and installation details before ordering.
