Delivery
Ball valves, rotary actuators, and mounting kits are not assembled and are delivered in
individual packaging.
Applications with auxiliary functions
A standard actuator with corresponding functionality can be used if a ball valve application
requires a rotary actuator with auxiliary functions (e.g. auxiliary switch or potentiometer). In
this case, mounting kit ASK77.x is required in
addition
to the rotary actuator.
Follow the mounting instructions when mounting.
