The actuators are suitable for attachment to Series V2001
Valves (e.g. Type 3321, Type 3323, Type 3531, Type 3535)
as well as Type 3214 and Type 3260 Valves. The actuators
mainly consist of two diaphragm cases, a rolling diaphragm
and internal springs. The Type 3372 Electropneumatic Actua
-
tor is controlled by a 4 to 20 mA signal. For throttling service,
an i/p converter is integrated into the actuator or a Type 3725
Positioner is mounted to the rod-type yoke using a support ele
