Description
Made for professional drill-rig and drifter maintenance, the Mechanical Valve (OEM 2651 6846 86) is positioned as a reliable aftermarket alternative for the pneumatic and compressed-air circuit. By managing pressure or flow at the required point in the circuit, it helps the machine maintain predictable hydraulic response during operation.
Precision at the spool, seat or cartridge interface helps preserve hydraulic response and consistent switching as operating pressure changes. For fleet maintenance, it offers a practical replacement route where dependable fit, serviceability and cost control are important. This reference is catalogued for equipment such as CDH 821C and CM 470; confirm the exact application before placing the order.
