Combining its core businesses in metallurgy and hydraulic machinery with industry technology trends, the valve body’s core technologies can be summarized into the following five key areas, suitable for heavy-duty and highly interfered industrial environments:
| Core technology | Technical Features | Performance advantages | Adaptation scenario |
|---|---|---|---|
| Heavy-duty wear-resistant structural design | The valve body is manufactured using an integral forging process with localized thickening. The sealing surfaces are overlay-welded with Stellite alloy or ceramic coatings, and the flow passages have been optimized to minimize impact wear. | With a pressure rating of up to 42 MPa, it resists particle erosion and boasts a service life three times longer. | Metallurgical slurry conveyance, blast furnace pulverized coal pipelines |
| Hydraulic-Servo Cooperative Control | The valve body integrates a proportional servo valve assembly, featuring built-in displacement and pressure sensors, supporting closed-loop feedback, and enabling coordinated control of the spool position in conjunction with the servo system. | Control accuracy: ±0.5%; response time < 0.3 seconds; reduced system integration costs. | Intelligent Hydraulic Station, Die Casting Machine / Injection Molding Machine Hydraulic Circuit |
| Harsh Environment Protection Technology | Designed with an IP67 protection rating, the valve body features a wear-resistant and corrosion-proof coating on its surface. The stem area employs a double packing gland plus a bellows seal. | Adaptability – Operates in temperatures ranging from 40℃ to 250℃, as well as in dusty and humid environments, with no risk of external leakage. | Outdoor mining equipment, metallurgical high-temperature areas |
| Customized Flow Channel and Sealing Technologies | Customized flow path curves are designed for different media (such as high-temperature oil and corrosive liquids), and the sealing pair adopts a metal-to-metal or metal-to-nonmetal composite structure. | Reduces flow resistance loss by more than 15%, suitable for special operating conditions, and features reliable sealing. | Chemical process control, building material production line batching systems |
| Digital Operations and Diagnostics | The valve body is equipped with built-in condition monitoring sensors and supports industrial buses (Profibus, Modbus), enabling remote monitoring of valve position, pressure, and sealing status. | Proactively warn of potential failures, extend maintenance cycles by 50%, and reduce downtime. | Continuous-operation heavy machinery, automated production lines |
Additional notes
1. Technology Benchmarking: Compared to general valve body manufacturers, Dirus places greater emphasis on structural reliability and hydraulic system synergy under heavy-duty operating conditions, rather than pursuing extreme lightweight design.
2. Verification Recommendation: Actual technical parameters (such as dielectric strength rating and sealing life) shall be based on the company’s test reports or third-party certifications. It is recommended to confirm these parameters through sample testing.
3. Patent Layout: It is speculated that the company may hold utility model patents related to the integration of valve bodies with servo systems, thereby enhancing the overall system performance.
