Descripción técnica completa

The 879 048 09 BALL VÁLVULA (87904809, 879-048-09, BALL VÁLVULA 87904809) is a mining-duty hydraulic shutoff válvula engineered for Sandvik equipo de perforacións, ROC series machines, and underground jumbos. The 879 048 09 BALL VÁLVULA provides precise on/off flow control, isolating hydraulic lines and maintaining stable circuit pressure during drilling, feed, rotation, and lubrication operations.

This 879 048 09 BALL VÁLVULA is built from corrosion-resistant, high-strength steel with a precision-machined spherical closure element designed to withstand extreme pressure, hydraulic oil exposure, abrasive mining dust, and continuous vibration. OEM identifiers 87904809 and 879-048-09 ensure compatibility with official Sandvik spare-parts documentation.

Función y funcionamiento

The 879 048 09 BALL VÁLVULA regulates hydraulic pathways in drifter assemblies, feed cilindros, manifold blocks, and lubrication circuits. Its quarter-turn actuation enables rapid and secure switching, preventing pressure spikes, backflow, and unintended hydraulic load on bombas, reténs, and actuators.

Fiabilidad y mantenimiento

Inspect the 879 048 09 BALL VÁLVULA for leakage, seat wear, handle stiffness, corrosion, or pressure decay. Replace 879 048 09 immediately if reténing integrity or switching reliability deteriorates.
