Products Description
Butterfly Valves for Oil-Immersed Transformer is a rotary valve used to control the flow of insulating oil inside the transformer. It is widely used in the oil circuit system between the main oil tank of the transformer and accessories (such as radiators, oil storage cabinets, cooling systems).
The main functions of oil immersed transformer butterfly valve：
| Function | Description |
|---|---|
| Oil Circuit On - Off Control | Controls the flow and shut - off of oil, for example, isolating the connection between the main oil tank and the radiator during maintenance |
| Facilitate Maintenance and Overhaul | When repairing components such as radiators and oil conservators, cut off the oil flow through a butterfly valve to avoid draining the entire transformer |
| Prevent Oil Backflow or Leakage | Install a butterfly valve in the oil circulation system to prevent oil backflow or leakage under abnormal working conditions |
| Oil Flow Switching or Flow Regulation | Used to adjust the oil flow rate in some systems to improve oil circulation efficiency |
