Description

Full Technical Description

The BALL VALVE 8202 0311 03 (8202031103, 8202-0311-03, BALL VALVE 8202031103) is a mining-duty hydraulic shutoff valve engineered for ATLAS COPCO and EPIROC drilling rigs, ROC series machines, and underground jumbos. The BALL VALVE 8202 0311 03 provides precise on/off flow control, isolating hydraulic lines and maintaining stable circuit pressure during drilling, feed, rotation, and lubrication operations.

This BALL VALVE 8202 0311 03 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 8202031103 and 8202-0311-03 ensure compatibility with official Epiroc/Atlas Copco spare-parts documentation.

Function & Operation

The BALL VALVE 8202 0311 03 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 BALL VALVE 8202 0311 03 for leakage, seat wear, handle stiffness, corrosion, or pressure decay. Replace 8202 0311 03 immediately if sealing integrity or switching reliability deteriorates.
