FAQ

DN40 refers to the nominal diameter (40mm) of the valve body it is designed to operate. The "SZ" is a German abbreviation, typically meaning "Schliessend mit Zuluft" (closes with air supply), indicating it is a spring-to-open / air-to-close actuator.

This actuator is specifically designed for the GEA Tuchenhagen VARIVENT modular valve system. While modifications might be possible, it is not guaranteed to be compatible with valve bodies from other manufacturers without custom adaptation.

Regular maintenance involves inspecting and replacing the piston seals and rod seals to prevent air leaks and ensure proper function. The frequency depends on the operating cycles, process media, and temperature. Always use food-grade lubricant suitable for the application.
