Why Choose Guangzhou Huilian?
| Features | Technical Support | Advantages |
| Ultra-fast response, with strike frequency consistently ranking among the top in the industry. | The directional valve has a response time of ≤18ms, is suitable for high flow rates of 40–70 L/min, and supports continuous operation of 500–900 bpm. | The hourly crushing capacity is increased by more than 25%, shortening the construction period and improving project profitability. |
| Zero internal leakage design, zero system pressure loss | The valve core and valve sleeve adopt a micron-level precision grinding + double-layer composite sealing structure, with an internal leakage of ≤3ml/min (measured value). | Hydraulic oil temperature rise is reduced by 15%, pump life is extended by 30%, and the risk of drill rod breakage due to pressure fluctuations is reduced. |
| Impact resistance and durability, 6 months of trouble-free operation | The valve body is made of high-strength alloy steel with surface nitriding treatment. It has undergone 1 million high-frequency commutation life tests without deformation or jamming. | Customer maintenance costs decreased by 40%, and annual downtime was reduced by 80 hours, truly achieving "one machine for all". |
| Full-condition adaptive, no lag during cold starts | With its built-in temperature-compensated flow channel design, it can establish stable oil pressure within 1 second even at a low temperature of -20℃. | In northern winters and high-altitude areas, it overcomes the "difficult start-up" problem and avoids the waste of "dry running" caused by thick oil. |
