Descripción técnica completa

The 551 796 87 BALL VÁLVULA (55179687, 551-796-87, BALL VÁLVULA 55179687) is a mining-duty hydraulic shutoff válvula engineered for Sandvik equipo de perforacións, ROC series machines, and underground jumbos. The 551 796 87 BALL VÁLVULA provides precise on/off flow control, isolating hydraulic lines and maintaining stable circuit pressure during drilling, feed, rotation, and lubrication operations.

This 551 796 87 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 55179687 and 551-796-87 ensure compatibility with official Sandvik spare-parts documentation.

Función y funcionamiento

The 551 796 87 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 551 796 87 BALL VÁLVULA for leakage, seat wear, handle stiffness, corrosion, or pressure decay. Replace 551 796 87 immediately if reténing integrity or switching reliability deteriorates.
