THINKTANK is proud to announce the successful delivery and commissioning of a DN2200 electric actuated hemispherical valve for a major hydraulic infrastructure project. The valve has been installed and is now operating smoothly on site. This milestone demonstrates THINKTANK’s capabilities in large-diameter valve design, precision manufacturing, and integrated electric actuation solutions for the water industry.
Engineering Challenge: Large Diameter, High Flow, and Long-Term Sealing Performance
The DN2200 hemispherical valve was designed for a long-distance water transfer system requiring high flow capacity and minimal pressure loss. While the valve does not operate frequently, it must maintain reliable performance under continuous service conditions. Key challenges included:
- Internal erosion prevention caused by high-velocity water flow,
- Structural integrity under constant water head pressure,
- Full-bore design to maximize flow capacity,
- Zero-leakage sealing over long service life,
- Stable and responsive electric actuation for infrequent but critical operations.
Technical Approach: Simulation-Based Design and Actuation Integration
THINKTANK’s engineering team applied advanced tools and methodologies to ensure the valve would meet demanding hydraulic conditions:
- 3D modeling and Finite Element Analysis (FEA) to confirm mechanical strength under operating pressures,
- Computational Fluid Dynamics (CFD) simulation to optimize internal flow path and reduce erosion risks,
- Precision-machined sealing surfaces and durable materials to ensure long-term tightness,
- Integrated electric actuator selected for high torque, low maintenance, and compatibility with remote operation.
Each design step was verified through simulation and validated with real-world performance testing prior to shipment.
Manufacturing and Delivery: Completed in Just 5 Months
Despite the complexity and scale of the project, THINKTANK completed the full production cycle in just five months, including:
- Custom mold development and large-scale casting,
- High-precision machining and quality inspection,
- Assembly of internal components and electric actuator,
- Factory acceptance testing (FAT) for flow, pressure, and sealing,
- Secure packaging and on-time delivery to the site.
This efficient execution ensured the client’s project timeline remained on track.
Customer Feedback: Stable Operation and Excellent Build Quality
Following commissioning, the client reported strong satisfaction with the valve’s performance:
“The valve is well designed and solidly built. Its sealing is tight, and the electric actuator works reliably. THINKTANK delivered a product that fully meets our expectations.”
