14. Electrical interface: conventional --- standard junction box type explosion-proof --- conventional lead type (standard length 1. 5m, Electrical interface conventional G1/2" external thread, other threads can also be customized), special junction box type

15. Can be equipped with explosion-proof type, explosion-proof mark ExdllCT5 Gb (certificate number: SYEx18. 0960X)

Product specification

The thread is usually G thread, and ZG (PT), NPT and other threads can also be customized according to user requirements.

       2. Flanges are manufactured according to GB/T9124 standard by default, and can also be manufactured according to user-specified standards.

            Such as JB/T79, HG/T20592, ANSI, JIS, DIN and other standards

       3. Z291 series normally closed solenoid valve and Z292 series normally open solenoid valve except coil configuration,

           Except for the difference in total height and weight, other parameters are the same.

       4. The bottom valve position signal feedback output can be customized for the bottom valve position signal feedback output in batches with conventional diameter ≥ DN25, and diameter < DN25.

       5. If the on-site installation space 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 valve DN65~1100 can be customized, please consult our customer service or sales staff for details.

       7. For details on the length of the valve body with manual operation, please consult our customer service or sales staff.
