Main Components
Housing
Housings for leakage bottom-seat valves are available with two, three, or four connection ports. The valves are produced with standard butt-weld connections by default. In addition to the regular bottom-seat housings, LVBS valves are also available with welded or screwed flange connections.
Internal Assembly
The internal assembly in its standard execution is equipped with a hard TEFASEP® seal for the axial, and an EPDM seal for the radial valve seat. In addition to the standard sealing material, also an o-ring made of PTFE is available for the axial valve seat seal.
Actuator
The pneumatic actuator for leakage valves LVBS is designed to be spring-closing/air-opening (NC). In addition to the full stroke, the standard design allows both valve seats to be lifted independently (EA). Optionally, the valve can be configured with an actuator where only the radial valve seat A can be lifted independently (AZ).
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
UltraClean leakage valves can be either equipped with open feedback units or T.VIS® feedback systems by default. Feedback units from third party suppliers can be mounted via specially designed adaptors.
Options
Aseptomag® Leakage Valves can be executed with an additional steam connection (DA), which enables intermediate steam flushing of the leakage area independent from any seat lifting.
Furthermore, a mechanical backstroke barrier (RSS) can be mounted on top of the pneumatic actuator. This unit interacts with the radial valve seat A and is used as an additional safety feature to maintain the mixproof valve functionality even in the event of pressure hammers up to 50 bar.

Aseptomag® Valve Technology
Double-chamber valve Aseptomag® DK – valve matrix
Aseptic bellows valves distinguish themselves with the uncompromisingly hermetic seal of the valve stem, thereby minimizing contamination risks and maximizing detection possibilities. The Aseptomag® valve line is the equivalent for sensitive process areas to the hygienic VARIVENT® valve line and provides everything from shut-off and bottom-seat to mixproof and sampling valves. The valves meet the highest hygienic standards and consider design guidelines such as EHEDG and 3-A standards. Thanks to the modular structure, the Aseptomag® valve line also allows tailor-made valve solutions for specific process requirements (higher closing pressures, special materials, special design, etc). Aseptomag® valves can be equipped with T.VIS® control tops and can therewith seamlessly be integrated into an automated process plant.
UltraClean Applications
Unlike the other valves in the Aseptomag® series, the main focus of the Leakage Valve LV and LVBS is not on purely aseptic but UltraClean applications. The most relevant product parameter for UltraClean applications is shelf-life. It is mostly determined by the pH-value and the aw-value of the product. In addition, sensory properties need to be considered as well as the logistical chain of distribution. One of the advantages of UltraClean processing is the reduced quantity of preservatives needed for maintaining the shelf-life of the product.
Application examples
- Dairy industry – Milk-based and lactic acid-fermented products (e.g. ESL milk, dessert products, crystallizing products such as lactose)
- Beverage industry – Water-, fruit and plant-based beverages (e.g. soft drinks, fruit juice, soy milk)
- Food industry – Sauces and delicacies
- Brewery industry – Beer and mixed beer beverages (e.g. pure yeast cultivation)
