Why Choose the AV-400?
The AV-400 eliminates the need for pre-assembled actuator-valve combinations by allowing technicians to field-assemble the MK-2690 actuator directly to the appropriate valve on-site. The inclusion of three spring ranges in a single kit provides maximum versatility, allowing the installer to select the correct spring for the pneumatic control signal present in the system — minimizing downtime and reducing the need for multiple part numbers.
