Aseptic Valves

For aseptic and sterile processes

– Hermetic separation of the valve interior by means of metal bellows

– Bellows with supporting element for:

•     Reducing vibrations in the process
•     Increasing the lifetime of the bellows

– Two-piece screwed-on valve disk optionally available:

•     Sealant material: EPDM/FKM/HNBR
•     Defined space for the sealing ring
•     Easy assembly without risk of twisting
•     Seal resistant to seepage and rip-out

– One-piece valve disk with sealing ring (PTFE compound) optionally available

– Connections for leakage drain/bellows monitoring

– Rotational decoupling on linkage between valve shaft and actuator for torsion-free lift motion of the valve disk

– Housing design for optimum cleaning and gentle product transfer

Fast and exact control of processes in sterile and aseptic applications

• Allocation of diaphragm actuator with adjustment to product pressure
• Selection according to nominal diameter, KV value and seat diameter
• Fine adjustment
• Diaphragm actuator with built-on positioner
• Control cone with equal percentage or linear
• Concept of sealing system as with Aseptic seat valve

Reliable separation in aseptic and sterile processes

– Safety when lifting the bottom valve disk with additional locking of the top valve disk

– Free cross-sectional areas in relation to the pipe diameter

– Tilted rinsing valve:

•     To protect the bellows
•     For optimum cleaning of the safety area

– Bellows with support:

•     Reduced vibrations in the process
•     Increased lifetime of the bellows

– Connections for leakage drain/bellows monitoring

– Actuator with integrated lift functions for:

•     Fast cycle times and low air consumption
•     Torsion-free lift motion of the valve disk
•     Rotational decoupling between valve shaft and actuator

– The option to arrange for the use of a temperature sensor permits the monitoring of the temperature directly in the housing

Direct connection to the tank without sump

• Metal bellows for hermetical sealing of the product room against the atmosphere
• One-piece housing, rotatable by 360°
• Independently working valve disks with their own sealing permit a reliable separation of incompatible media. The safety chamber between the valve disks is connected via flushing valves.
• Cleaning/sterilisation of the safety chamber is effected via the flushing valves or by actuating the upper or lower valve disk
• Free cross-sectional areas in the valve housing permit gentle product guidance
• Allocation of actuator with adjustment to product pressure
• Integrated lifting features of the actuator permit fast cycle times and low air consumption
• Sealing geometry optimised for all applications
• The option to arrange for the use of a temperature sensor permits the monitoring of the temperature directly in the housing

Safe and sterile withdrawal of product samples

– Optional design as fixed valve or as flexible sampling system

– Valve version with tank connection stub, welded end or for inline installation

– Bellows seal: PTFE-TFM 1705

– Actuation variants

•     Pneumatic actuator
•     Hand lever in self-closing design
•     Handwheel for fine adjustment

– Monitoring with optional use of a proximity switch
