Description

Created for continuous-duty rock drilling applications, the Overcenter Cartridge (OEM 3222 3117 86) offers a service-focused replacement choice for the hydraulic power and control circuit. The component regulates a defined part of the fluid circuit, supporting controlled actuator movement and protection of connected hydraulic elements.

Precision at the spool, seat or cartridge interface helps preserve hydraulic response and consistent switching as operating pressure changes. Cross-reference data lists applications including FLEXIROC D60LF and FLEXIROC D60SF; final fit should be confirmed against the machine configuration or serial information. As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel.

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 120 200 112 and OEM reference 3222 3117 86.
