ReliefValve

Engineered for reliable service on rock drilling equipment, the ReliefValve (OEM 040300-01012) is an aftermarket replacement for Furukawa rock drilling and related equipment. It manages hydraulic or pneumatic flow, direction and pressure so the connected circuit can respond predictably to operator commands. It is cross-referenced for equipment including HCR 1200, HCR 1200-EW and HCR 1500-D20.

The replacement is intended to perform under continuous pressure changes, fluid flow, switching cycles and vibration. The use of precision-machined flow passages and closely controlled internal interfaces supports consistent fit at the relevant interfaces and reliable operation after replacement. In practical maintenance terms, this supports accurate circuit control, consistent actuator response and dependable hydraulic performance.

Supplied as a Delkom aftermarket alternative, this part gives maintenance teams a practical cross-reference option for Furukawa drilling equipment. Use Delkom reference 130 200 074 when requesting availability, quantity pricing or technical support.
