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. The parameters of Z291 series NC solenoid valves are the same as Z292 series NO solenoid valves except the coil configurations, height and weight.
4. The feedback 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.
5. If the installation space on site is limited, the radiator type can be selected, and the height dimension of the radiator type is reduced by 70mm from the value in this table.
6. Z291, Z292 series solenoid valves can be customized for DN65~1100, please consult our customer service or sales for details.
7. For the length of solenoid valve with manual device, please consult our customer service or sales for details.
