Description

When uptime and correct fit are priorities, the Press. Relief Valve (OEM 551 737 19) provides an alternative spare-parts 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.

Precision at the spool, seat or cartridge interface helps preserve hydraulic response and consistent switching as operating pressure changes. The alternative sourcing option is suited to maintenance programs focused on equipment availability, predictable servicing and competitive lifecycle cost. Application data associates this reference with DD311-40 and DD321-40; configuration and serial-number checks are recommended before purchase.

Within Delkom’s rock-drilling replacement-parts portfolio, this item is intended to support reliable maintenance and efficient global sourcing. Include Delkom reference 200 200 262 and OEM reference 551 737 19 in your enquiry for an accurate quotation.
