Notes:

1. G thread is the conventional thread, ZG (PT), NPT and other threads can be customized according to users´ requirements.
2. The flange is manufactured according to GB/T9124 standard by default, can also be manufactured according to the standards specified by users, such as JB/T79-1994, HG/T20592, ANSI, JIS, DIN and other standards.
3. DN01~50 with conventional threaded connection (no carbon steel valve body for valves with DN＜25), DN15~300 with flange connection (no carbon steel valve body for valves with DN＜25). 4. The parameters of Z291 are the same as Z292 except the coil configurations and height.
5. The output of bottom valve position signal is normally equipped for valves with DN≥25, the feedback output can be customized in batches for valves with DN＜25, while the output of top valve position signal has no diameter limit.
