Mounting kits (attachment kits)
The attachment kit is the link between valve and rotary actuator with an interface according to DIN EN ISO 5211 or VETEC standard and contains the following components:
- Console or bracket → depending on valve series
- Lever kit
- Screws for fastening to the valve
- Screws for mounting the actuator
- Optional mechanical end stops ( rotation angle limitation)
- Position indicator
- Protective cover (cover plate)
Mounting arrangements
Type MN actuators may only be installed, transported, lifted or stored in a vertical orientation (upwards).
We recommend mounting types B and D for mounting the actuator. Mounting types A and C only on request!
Mounting type B is selected as the standard mounting position if no other information is available.
Exemplary illustration of mounting type B. For other mounting types, see data sheet TY005.009.
FC = Spring closes • FO = Spring opens • FTO = Medium opens (flow from the front, from the seat side) • FTC = Medium closes (flow from the rear)
Accessories
The control valves can be equipped with various accessories: Positioner, solenoid valve, supply pressure regulator, limit switch, volume booster/booster and other attachments.
Mounting of accessories (attachments) to pneumatic rotary actuators is performed according to two standardized mounting methods:
