Description

Developed as a practical replacement option for hard-working drill rigs and drifters, the One-Way Restrictor (OEM 806 981 89) is used within the rock drilling machine assembly. By managing pressure or flow at the required point in the circuit, it helps the machine maintain predictable hydraulic response during operation.

The alternative sourcing option is suited to maintenance programs focused on equipment availability, predictable servicing and competitive lifecycle cost. Compatibility records include AXERA 5-126 and AXERA 6-240. For best results, check the part reference together with the machine model and serial data. Controlled internal clearances, sealing surfaces and flow passages are important for predictable response and reduced internal leakage across repeated pressure cycles.

Delkom combines rock-drilling spare-parts expertise with broad export capability for mining and tunneling customers. For purchasing support, bulk requirements or fitment confirmation, use Delkom reference 200 200 037 and OEM reference 806 981 89.
