Valve C1200022861 is a critical pressure-regulating and flow-control component for Hydraulic Rock Drills. It excels in extreme mining environments—for instance, deep underground ore mines, high-altitude hard rock quarries and large-scale tunnel boring projects.
These settings pose intense vibration (up to 48G), abrasive rock dust, corrosive hydraulic oil and drastic temperature swings. Yet, Valve C1200022861 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations and cause hydraulic system failures.
First, its 316L stainless steel body + ceramic valve core resists wear and corrosion. This eliminates premature failure from abrasive particles in hydraulic oil. Second, it withstands 60MPa working pressure without leakage. Consequently, it ensures stable pressure output for drill impact and rotation functions. Third, its ±0.05% flow precision enables precise control of drilling speed. likewise, this improves drilling accuracy and reduces material waste.
Fourth, the double-seal (PTFE + metal gasket) anti-leak design blocks oil seepage. Above all, this prevents hydraulic oil loss and environmental pollution in mining sites. Fifth, the temperature-compensated spool design adapts to extreme temperature changes. On top of that, it maintains consistent performance in both low-temperature high-altitude and high-temperature deep mining environments.
Unlike ordinary hydraulic valves, this model combines corrosion-resistant materials with precision machining. To elaborate, the ceramic valve core reduces friction coefficient to 0.03, while the 316L steel body resists chemical erosion. Thus, it outperforms standard valves in service life by 130%.
Our manufacturing team uses precision CNC machining + lapping technology for valve seats. Furthermore, the surface undergoes anti-corrosion treatment, enhancing durability in harsh environments. Additionally, flow calibration tests ensure ±0.05% precision, meeting strict hydraulic system requirements.
Notably, it adapts to extreme temperatures from -90°C to 230°C. Moreover, it passes 350-hour salt spray tests with no rust or valve sticking. In addition, it endures 700,000-cycle switching trials without performance degradation.
The valve’s flange connection design integrates seamlessly with mainstream Hydraulic Rock Drill hydraulic systems. It requires no modifications to existing pipelines. As a result, maintenance teams can complete installation in 12 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure tests, flow precision checks, leak-proof trials and corrosion resistance inspections. Importantly, it complies with ISO 4401 international hydraulic valve standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its durability, it reduces replacement frequency by 92%. Additionally, backed by a 12-month warranty, it cuts valve-related failure rates by 95%.
It not only extends hydraulic system service life by 90% but also lowers annual maintenance costs by 60%. Overall, Valve C1200022861 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it ensures precise control of drilling parameters, maximizing operational efficiency and project profitability.
