Description

Full Technical Description

The 819 081 99 VLVULA DE ESFERA (81908199, 819-081-99, BALL VALVE 81908199) is a mining-duty hydraulic shutoff valve engineered for Sandvik drilling rigs, ROC series machines, and underground jumbos. The 819 081 99 VLVULA DE ESFERA provides precise on/off flow control, isolating hydraulic lines and maintaining stable circuit pressure during drilling, feed, rotation, and lubrication operations.

This 819 081 99 VLVULA DE ESFERA 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 81908199 and 819-081-99 ensure compatibility with official Sandvik spare-parts documentation.

Function & Operation

The 819 081 99 VLVULA DE ESFERA 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 819 081 99 VLVULA DE ESFERA for leakage, seat wear, handle stiffness, corrosion, or pressure decay. Replace 819 081 99 immediately if sealing integrity or switching reliability deteriorates.
