Main components
Welded flange
For both the mechanical and pneumatic versions, the welded flange is identical and fixed to the valve using four screws.
Internal Assembly
The contact force of the valve seat seal is adjusted using an adjusting nut in the case of valve type DE. In the case of valve type DE PA, adjustment takes place using compressed air in the actuator. All internal assemblies are equipped with a Tefasep® seal by default.
Actuator
Steam inlet valves DE do not have an actuator. Valve type DE PA, on the other hand, is equipped with an air-closing / air-opening pneumatic actuator (LL).
Clamp
Due to its solid construction, the GEA Aseptomag clamp enables a pressure stable and safe connection of the main components. The special design with three segments allows a service-friendly handling of the component, even under tight space conditions.
Feedback units
Steam inlet valves type DE PA (with pneumatic actuator) can be either equipped with feedback units or T.VIS® feedback systems by default. Feedback units from third party suppliers can be mounted via specially designed adaptors. To find out more about feedback units, please click here.
Steam inlet valves type DE are directly welded between a tank and a pipe system and can therefore not be equipped with any feedback options.
