VESTA® valve line
Sampling Valves VESTA® H_A/I
VESTA® sampling valves are used for sampling from product pipelines or vessels in aseptic processing plants.
Sampling Valve VESTA® H_A_I – adaption to VARINLINE® housing
Main Components
Housing
Housings for VESTA® sampling valves can either be executed with a housing connection flange or with a VARINLINE® transfer housing. On the extraction side, valve housings withone (execution L) or two (execution T) connection ports are available. The connection ports on the extraction side are available in three different pipe classes and two nominal diameters each.
The housing connection flange is used for the flush-mounted, dead-space-free adaption of VESTA® sampling valves in the vessel wall or in the dished vessel end. Process integration via a VARINLINE® housing can be achieved with process connections of different sizes; the housing for the process line is always designed for media transfer.
Internal Assembly
The PTFE bellows for VESTA® sampling valves distinguish themselves from others by an extended cylindrical section in the seat area. Furthermore they always have a flat end towards the product pipeline.
Actuator
The actuator can be executed pneumatically or manually. The manual version is made of plastic in all cases. Pneumatic actuators are available in plastic or stainless steel, and the fail-safe (normally close or normally open) position can be easily reversed.
Control and feedback systems
Pneumatic actuators include a visual valve status indicator by default. Alternatively, visual indicators can be replaced by an open feedback unit or by using the adequate adaptor plate with a T.VIS® control and feedback system in various executions.

VESTA® Sterile Valves
Shut-off valve VESTA® H_A – valve distribution bulkhead connection
Thanks to the hermetic sealing of the valve stem with a PTFE bellows, VESTA® sterile valves provide a maximum level of process line isolation and therewith contribute to customers’ product and process safety.
The VESTA® valve series is specifically designed to meet the highest requirements for sterile processes in the pharmaceutical, biotech and cosmetics industry. The valve program provides everything that is required to ideally serve these industries. The high-quality valve range consists of different valve types, and thanks to the modular build-up, the valves can also be tailor-made for specific process conditions and still meet all requirements from a regulatory point of view.
VESTA® valves can be seamlessly integrated into an automated process plant by using the T.VIS® control tops.
PTFE bellows as key element
VESTA® - PTFE bellows
Key element of VESTA® sterile valves is a single-piece PTFE bellows made of the material TFM 1705. Adding to its excellent chemical resistance against almost all media, TFM 1705 also complies with all standards relevant for the pharmaceutical industry, such as e.g. FDA 21 CFR 177.1550 and USP class VI. The high-value surface finish (Ra ≤ 0,8 μm), the seamless and hermetic sealing as well as the CIP/SIP optimized design are other characteristic features. The patented bellows sealing system safely separates the product-wetted area from the atmosphere in all process steps and furthermore seals the valve seat.
