VÁLVULA DE ESFERA

The 764746 BALL VÁLVULA (764746, 007-647-46, BALL VÁLVULA 764746) is a mining-duty hydraulic shutoff valve engineered for Sandvik drilling rigs, ROC series machines, and underground jumbos. The 764746 BALL VÁLVULA provides precise on/off flow control, isolating hydraulic lines and maintaining stable circuit pressure during drilling, feed, rotation, and lubrication operations.

This 764746 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 764746 and 007-647-46 ensure compatibility with official Sandvik spare-parts documentation.

The 764746 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.

Inspect the 764746 BALL VÁLVULA for leakage, seat wear, handle stiffness, corrosion, or pressure decay. Replace 007 647 46 immediately if sealing integrity or switching reliability deteriorates.
