AI Technical Summary
Existing five-way valves have low control accuracy, slow response speed, complex structure, poor sealing performance, and are prone to leakage, making it difficult to achieve high-precision fluid control.
The valve core features a tight-contact design between the valve core sealing gasket and the valve core, forming a physical isolation layer when the actuator is not powered on, blocking fluid communication between channels. Combined with the sealing ring, the valve stem continuously seals the penetration points during rotation, ensuring a double sealing effect.
It effectively avoids internal and external leakage, ensuring high-precision fluid control. It has a simple structure, is easy to operate, and improves the accuracy and stability of fluid control.
