Press. Relief Valve

Description

Designed to support reliable field operation and planned overhauls, the Press. Relief Valve (OEM 551 796 62) provides an aftermarket solution for the hydraulic power and control circuit. By managing pressure or flow at the required point in the circuit, it helps the machine maintain predictable hydraulic response during operation.

Controlled internal clearances, sealing surfaces and flow passages are important for predictable response and reduced internal leakage across repeated pressure cycles. Application data associates this reference with DD321-40 and DT821C; configuration and serial-number checks are recommended before purchase. For overhaul and repair planning, the component provides a competitive alternative to original-supply-only purchasing.

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 200 200 135 together with OEM reference 551 796 62.
