Description

Engineered around the operating needs of surface and underground drilling equipment, the Press. Reducing Valve (OEM 550 544 97) is an aftermarket component for the hydraulic power and control circuit. Its function is to direct, meter or limit fluid flow and pressure so the related hydraulic functions respond in a controlled and repeatable manner.

As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel. Typical listed applications include DD321-40 and DT821-C, subject to machine specification and configuration verification. Precision at the spool, seat or cartridge interface helps preserve hydraulic response and consistent switching as operating pressure changes.

This component forms part of Delkom’s alternative spare-parts program for professional drilling machinery. For current stock, commercial terms and technical cross-checking, quote Delkom part number 200 200 214 with OEM reference 550 544 97.
