Relief Valve

Engineered around the operating needs of surface and underground drilling equipment, the Relief Valve (OEM 040300-480050) is an aftermarket component for the hydraulic power and control circuit. It contributes to stable circuit behavior by controlling the direction, pressure or rate of hydraulic flow according to the valve function.

Controlled internal clearances, sealing surfaces and flow passages are important for predictable response and reduced internal leakage across repeated pressure cycles. Compatibility records include HCR 1450-ED and HCR L90s-E5. For best results, check the part reference together with the machine model and serial data. The part supports cost-conscious maintenance strategies that require a reliable cross-reference option for professional drilling equipment.

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 200 200 192 and OEM 040300-480050 when contacting the Delkom team.
