| Main Material | Commonly used are cast iron, carbon steel, stainless steel. Oil - immersed transformers are mostly equipped with brass or cast steel with epoxy anti - corrosion coating. |
| Sealing Material | Oil - resistant rubber (such as NBR, EPDM), PTFE, etc., to ensure no leakage when immersed in transformer oil for a long time. |
| Actuation Method | Mostly manual with a handle. There are also a few models of electric/pneumatic butterfly valves (for large transformers or remote control). |
| Connection Method | Mainly flange connection (DIN/ANSI standard), and there are also a few threaded connection types. |
| Valve Opening Indication | Some are equipped with switch indicators or locking devices to improve operational safety. |
