Description

Full Technical Description

The 551 646 04D BALL VALVE (55164604d, 551-646-04d, BALL VALVE 55164604d) is a mining-duty hydraulic shutoff valve engineered for Sandvik drilling rigs, ROC series machines, and underground jumbos. The 551 646 04D BALL VALVE provides precise on/off flow control, isolating hydraulic lines and maintaining stable circuit pressure during drilling, feed, rotation, and lubrication operations.

This 551 646 04D 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 55164604d and 551-646-04d ensure compatibility with official Sandvik spare-parts documentation.

Function & Operation

The 551 646 04D 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 551 646 04D BALL VALVE for leakage, seat wear, handle stiffness, corrosion, or pressure decay. Replace 551 646 04d immediately if sealing integrity or switching reliability deteriorates.
