CHECK VALVE

The CHECK VALVE 3115 5189 00 (also indicated as 3115518900 and 3115-5189-00) is a mining-grade hydraulic check valve engineered for use in Epiroc and Atlas Copco drilling rigs, ROC-series platforms, and underground jumbos. The CHECK VALVE 3115 5189 00 allows fluid flow in one direction while preventing reverse flow, ensuring stable hydraulic pressure and preventing system backfeeding during drilling, feeding, and tramming operations.

This CHECK VALVE 3115 5189 00 is manufactured with precision-machined valve seats, hardened sealing surfaces, and corrosion-resistant internals designed to withstand high pressure, vibration, shock pulses, hydraulic oil contamination, and extreme temperature changes common in mining environments. OEM identifiers 3115518900 and 3115-5189-00 confirm full compatibility with Atlas Copco and Epiroc hydraulic networks.

The CHECK VALVE 3115 5189 00 maintains directional hydraulic flow integrity, protecting pumps, actuators, feed cylinders, and rotation systems from pressure spikes and unintended reverse flow. Stable check valve performance is essential for accurate drilling response, safety, and component longevity.

Inspect the CHECK VALVE 3115 5189 00 for leakage, contamination buildup, sticking, or seat wear. Replace 3115 5189 00 immediately if pressure drops, delayed response, or reverse flow symptoms appear.
