Description

Created for continuous-duty rock drilling applications, the Relief Valve (OEM 040300-350020) offers a practical aftermarket replacement option for the hydraulic or pneumatic control circuit. The component regulates hydraulic, pneumatic or accumulator behavior so pressure and flow remain controlled during operation.

Precision flow passages, sealing interfaces and pressure-bearing surfaces support accurate control under repeated hydraulic or pneumatic cycling. Among the listed compatible applications are DCR 20 and HCR 1200-DSIII, supporting easier cross-reference during maintenance planning. The part offers an alternative sourcing option for fleets focused on equipment availability, predictable maintenance and competitive operating cost.
