Description

Supporting maintenance teams working in abrasive, vibration-intensive environments, the Insert (OEM 3128 3023 71) is used in 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.

As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel. Controlled internal clearances, sealing surfaces and flow passages are important for predictable response and reduced internal leakage across repeated pressure cycles. Cross-reference data lists applications including BOLTEC 235 and BOLTEC 235H; final fit should be confirmed against the machine configuration or serial information.

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 200 200 109 and OEM reference 3128 3023 71.
