Full Technical Description
The 049 103 57 BALL VALVE (4910357, 491-035-7, BALL VALVE 4910357) is a mining-duty hydraulic shutoff valve engineered for Sandvik drilling rigs, ROC series machines, and underground jumbos. The 049 103 57 BALL VALVE provides precise on/off flow control, isolating hydraulic lines and maintaining stable circuit pressure during drilling, feed, rotation, and lubrication operations.
This 049 103 57 BALL VALVE 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 4910357 and 491-035-7 ensure compatibility with official Sandvik spare-parts documentation.
Function & Operation
The 049 103 57 BALL VALVE 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.
Reliability & Maintenance
Inspect the 049 103 57 BALL VALVE for leakage, seat wear, handle stiffness, corrosion, or pressure decay. Replace 491 035 7 immediately if sealing integrity or switching reliability deteriorates.
