Valve Block

Built around the service demands of rock drilling machinery, the Valve Block (OEM 9106 1078 40) provides an aftermarket replacement path 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.

As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel. Accurate valve geometry supports stable flow control, while robust working surfaces are intended to tolerate vibration, pressure variation and contaminated field environments. Listed compatible equipment includes BOLTEC MC and BOLTEC MD. Verify the exact machine variant before installation or ordering.

Delkom supplies alternative spare parts for rock drilling equipment to maintenance teams across international mining and tunneling markets. When requesting stock status, technical support or a quotation, provide Delkom part number 120 200 269 together with OEM reference 9106 1078 40.
