Q810 Actuator Data Table

1.See P120-139 of this manual for QA, QH, QW series pneumatic actuator data table

Dimension (Flanged Pn16bar)

Notes:

The flange is manufactured according to GB/T9124 standard by default, and can also be manufactured according to the standards specified by users, such as JB/T79-1994, HG/T20592, ANSI, JIS, DIN and other standards.
See the dimension of Electric Butterfly Valve on P077 of this manual for the detailed dimension of wafer type.
In the above table, DN50~500 dimension is the dimension when equipped with QAS double-acting actuator, DN600~1400 dimension is the dimension when equipped with QWS double-acting actuator. If selecting QAD, QHS, QHD and QWD series actuators, please refer to the dimensions of each actuator.
