One-way Throttle Valve C1200031691 is a critical hydraulic flow control component exclusively designed for Hydraulic Rock Drills. It excels in harsh mining environments—for instance, underground hard rock mines, high-altitude quarries, tunnel construction sites and drilling areas with contaminated hydraulic oil.
These settings pose unique challenges for one-way throttle valves: high hydraulic pressure fluctuations, hydraulic oil contamination (metal particles), frequent flow adjustment, vibration (up to 35G), and temperature swings. These issues often cause valve clogging, flow control inaccuracy, reverse flow, or leakage, leading to drill actuation instability and costly downtime. Yet, One-way Throttle Valve C1200031691 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its stainless steel 304 valve core + brass valve body withstands 32MPa working pressure and 64MPa burst pressure. This eliminates valve rupture or leakage caused by pressure spikes in drill hydraulic systems. Second, the ±2% flow control precision ensures accurate adjustment of drill actuation speed. Consequently, it improves drill positioning accuracy by 25% compared to standard throttle valves. Third, the anti-clogging valve core design (large flow channel + filter screen) prevents blockage from hydraulic oil contaminants. Likewise, this reduces maintenance frequency and extends service life by 130%.
Fourth, the integrated one-way check function blocks hydraulic oil reverse flow when the drill stops. Above all, this prevents drill component damage from unexpected movement and ensures operational safety. Fifth, the wide temperature adaptability (-25°C~110°C) ensures stable performance in cold high-altitude mines and hot underground drilling environments. On top of that, the stainless steel 304 valve core resists corrosion from acidic hydraulic oil additives, enhancing durability in long-term use.
Unlike ordinary industrial one-way throttle valves, this model is engineered for Hydraulic Rock Drills’ dynamic working conditions. To elaborate, the anti-clogging flow channel matches the drill’s hydraulic oil contamination characteristics, while the ±2% flow precision adapts to drill actuation requirements. Thus, it outperforms generic valves in service life by 140%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision CNC machining + ultrasonic cleaning technology for the valve core and body. Furthermore, each unit undergoes 32MPa pressure testing (25 minutes) and flow control precision verification. Additionally, the valve undergoes 80,000-cycle flow adjustment trials to ensure no performance degradation.
Notably, it adapts to extreme temperatures from -25°C (high-altitude cold regions) to 110°C (high-load drill hydraulic systems). Moreover, it passes 400-hour salt spray tests with no corrosion or rust. In addition, it endures 5,000-hour hydraulic oil immersion trials without seal aging or leakage.
The valve’s standard BSPP thread connection integrates seamlessly with mainstream Hydraulic Rock Drill hydraulic systems. It requires no modifications to existing pipelines or control panels for installation. As a result, maintenance teams can complete replacement in 15 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure resistance tests, flow precision inspections, anti-clogging trials and reverse flow verification. 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 reliability, it reduces valve-related failure rates by 94%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 58%.
It not only ensures precise flow control for drill hydraulic systems but also extends the service life of drill actuation components by 85%. Overall, One-way Throttle Valve C1200031691 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by valve failure, maximizing operational efficiency and project profitability.
