Characteristics
This motorized wafer soft seal butterfly valve adopts high quality rubber soft sealing structure to achieve bidirectional zero leakage with flexible and reliable fitting. The ultra-thin lightweight wafer design saves installation space and reduces construction costs. Equipped with a stable electric actuator, it supports precise on/off and modulating control for automatic pipeline operation. It is widely used in water supply, drainage, HVAC and general industrial fluid systems.
Advantages
1.Excellent sealing performance, zero leakage bidirections:
Premium soft seal provides flexible fitting and excellent tightness. It adapts to pipeline deviation and pressure fluctuation to achieve reliable bidirectional zero leakage.
2.Electric precision self-control, wide universality:
Ultra-light wafer structure saves installation space, reduces pipeline load and construction cost with easy disassembly and maintenance.
3.Lightweight and space-saving, with low installation cost:
Stable electric operation supports local and remote automatic control and proportional regulation, suitable for various general water supply and ventilation pipeline systems.
Packing
Standard export wooden case packaging
Application Scenarios
The electric wafer butterfly valve widely used in municipal water supply and drainage, central air conditioning HVAC systems, fire water supply, sewage treatment, pure water process, ventilation and industrial circulating water pipelines.
