Description
Main Components
- Housing: The height of the dead-space-free housing exactly corresponds to the diameter of the connection pipeline and therewith avoids domes and sumps. Numerous housing combinations based on a clamped seat ring design are available.
- Internal Assembly: The hermetically sealing D-tec® stem diaphragm is the key element of a D-tec® valve. It is characterized by a very long service life and high dimensional stability with temperature resilience and cleanability. The valve seat can be executed wih a metallic stop, with a soft-sealing (i.e. EPDM) or a hard-sealing (TEFASEP® gold) valve seat seal. D-tec® Control valves provide equal-percentage control cone characteristics and different Kvs values are available for each valve size.
- Actuator: The actuator size, which is chosen based on process and installation requirements, contributes to low air and energy consumption. Depending on the valve task, various actuator options are available and the valve can be ideally adapted to customer requirements. The actuator contains an integrated interface for mounting a T.VIS® position controller by default and the internal air supply reduces the risk of failure with external hoses.
- Lantern: The lantern connects actuator and product parts and simultaneously prevents the system from heat transfer between these two valve sections. The lantern has an important supporting and clamping function for the D-tec® stem diaphragm and is furthermore designed for a safe and easy visual detection of leakages.
- Position Controller: D-tec® control valves are equipped with T.VIS® P-15 position controllers by default. They enable seamless integration of the valves into an automated processing plant.
