Main applications
Heating System
Used to regulate the flow of hot water through heating pipes, ensuring consistent temperature control in individual rooms or zones.
Underfloor Heating System
Manages the distribution of hot water to different areas, optimizing the efficiency and performance of the underfloor heating system.
Air Conditioning System
Controls the flow of chilled water or air to enhance cooling performance and improve overall air conditioning efficiency.
Other Applications
Can also be applied in water treatment systems, fire sprinkler systems, industrial pipelines, and various other environments where fluid control is needed.
FAQ
Can the valve become stuck if there are solid impurities in the pipeline?
Yes, small particles can obstruct the valve, potentially causing it to get stuck. It is advisable to install a filter before the valve to prevent blockages and ensure smooth operation.
Is the valve suitable for use with corrosive fluids?
For corrosive fluids, it is recommended to opt for a stainless steel valve and use a corrosion-resistant seal, such as PTFE, to ensure durability and prevent damage.
How can I prevent the valve from getting stuck if it's not used for a long time?
To prevent sticking, it is helpful to operate the valve periodically. Alternatively, selecting an electric actuator with an anti-sticking feature can further ensure smooth functionality over time.
Can this valve perform reliably in a vibrating environment?
While the valve is designed to work in a vibrating environment, it is advisable to install a shock absorber to prolong the system's lifespan and enhance its stability.
How can I tell when the valve's seal needs replacement?
If the valve continues to leak even when it is fully closed, it is likely that the seal is worn out and needs to be replaced promptly to maintain optimal performance.
