Description

Built around the service demands of rock drilling machinery, the Overcenter Valve (OEM 550 422 09) provides an aftermarket replacement path 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 DX700 and DX800; 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.

Offered within Delkom’s aftermarket range for surface and underground drilling machinery, this part supports planned maintenance and international spare-parts supply. To confirm availability and fitment, reference Delkom 200 200 036 and OEM 550 422 09 when contacting the Delkom team.
