Descrição

Descrição técnica completa

The 806 801 89 BALL VÁLVULA (80680189, 806-801-89, BALL VÁLVULA 80680189) is a mining-duty hydraulic shutoff valve engineered for Sandvik drilling rigs, ROC series machines, and underground jumbos. The 806 801 89 BALL VÁLVULA provides precise on/off flow control, isolating hydraulic lines and maintaining stable circuit pressure during drilling, feed, rotation, and lubrication operations.

This 806 801 89 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 80680189 and 806-801-89 ensure compatibility with official Sandvik spare-parts documentation.

Função e funcionamento

The 806 801 89 BALL VÁLVULA regulates hydraulic pathways in drifter assemblies, feed cylinders, manifold blocks, and lubrication circuits. Its quarter-turn actuation enables rapid and secure switching, preventing pressure spikes, backflow, and unintended hydraulic load on pumps, seals, and actuators.

Fiabilidade e manutenção

Inspect the 806 801 89 BALL VÁLVULA for leakage, seat wear, handle stiffness, corrosion, or pressure decay. Replace 806 801 89 immediately if sealing integrity or switching reliability deteriorates.
