FAQ
1. What is the impact of the difference in Kv value on the control accuracy of hot and cold water flow, and how to select the appropriate model?
Kv value is the flow coefficient, which reflects the flow capacity of the valve. For small flow and precise temperature control scenarios, choose a low Kv value to avoid flow fluctuations; for large flow systems, choose a high Kv value to ensure smooth water flow. It is necessary to match the system flow and pressure requirements to ensure flow control accuracy.
2. How is the corrosion resistance and performance stability of the forged brass valve body in hot and cold water alternation and high humidity environments?
Forged brass has a good foundation for hot and cold water corrosion resistance. The product design is suitable for conventional hot and cold water alternation scenarios, and the corrosion resistance and performance retention are reliable under ambient temperature 0-65℃ and non-condensing conditions. It is recommended to avoid contact with strong corrosive media and clean the surface water vapor impurities daily, so that it can operate stably for a long time and meet the needs of hot and cold water control.
3. The motor torque is >800gf.cm. When it is frequently switched on and off for a long time, what are the risks of motor durability and performance degradation?
The motor torque design meets the needs of frequent start and stop. Under rated conditions, it has been tested and verified in practice that the durability is reliable, and the internal structure can output torque stably. If it is operated beyond the working conditions, it may affect the life. When used in accordance with the regulations, the performance stability of long-term frequent switching can be guaranteed.
4. If there are installation adaptation problems or later failures after purchase, what is the after-sales process?
Before installation, if the model and specifications do not match, if it is not installed and does not affect the secondary sales, you can contact after-sales to coordinate replacement; after installation or during use, if there is a failure, attach on-site photos and fault descriptions when giving feedback, the after-sales team will respond quickly, remotely guide the investigation, and arrange technicians to repair and replace accessories on site when necessary to ensure use.
