Structure Diagram and Component and Material Table

Notes:

Upper valve body and lower valve body are thread connected, adopting sealing gasket and sealant with excellent performance, when dissembling lower valve body, please melt the sealant first then loose the thread.
The single acting is normal mode by default, double acting is special mode.

Dimension

Notes:

The thread connection is G=Rp by default and ZG=PT=Rc, NPT and other threads can be customized according to users´ requirements.
The flange is manufactured according to JB/T79-1994 standard by default and can also be manufactured according to the standards specified by users, such as GB/T9124, HG/T20592, ANSI, JIS, DIN and other standards.
The configuration of the above NC (single or double acting) actuator is for normal applicable pressure: 0～8bar, for special 8～16bar type, actuator should be configured with a one-increment larger cylinder; NO double acting actuator is for normal applicable pressure: 0~8bar, for special 8～16bar type, actuator should be configured with a one-increment larger cylinder; NO single acting actuator is for normal applicable pressure: 0～3bar, types above 3bar are not recommended.
