Hygienic process valves
On/off and modulating control valves for hygie-nic processing and manufacturing applications. All hygienic valve types, including seat valves, double-seat valves, butterfly valves, and ball valves, are offered with finishes to suit aseptic systems. The modular assemblies offered utilise Bürkert’s universal controllers, which integrate pneumatics, feedbacks, network interfaces, and direct programing touch-pads for streamlined cross-site functionality. These electronics can also be utilised with valves on ancillary processes.
This datasheet details the following valves, with other configurations on request:

These valves are designed for shut off, and changeover, in hygienic processes. They are pneumatically operated, with one or two valve bodies that easily clamp together. These valves are approved according to EHEDG guidelines.
These hygienic seat valves each operate with both the on/off 8691 controller, and the 8692 modulating (proportional) controller.

The RV-ST integrates Bürkert’s digital positioner Type 8692, or positioner process-controller Type 8693, with the second-generation Alfa Laval hygienic single seat regulating valve. Built on a proven history, the RV-ST assembly valve offers high volume sanitary processing and regulation, and is particularly indicated where precision flow control is required.

Valve sizing: Flow Coefficients
The following formula and flow coefficient values enable you to select the correct regulating valve for your application.
Formula for water, and other media with a specific gravity equal to 1.0:
Formula for media with a specific gravity other than 1.0:
kv = Q. 1∆p/SG
kv = Q. 1∆p

Bürkert: partners in the hygienic world
Robolux system valves
Robolux is a high-tech solution for hygienic process
environments where footprint and dead volume must be
minimised. The valves incorporate multiple functions
within one unit, can be offered with stainless steel
actuator, and assemble with Bürkert control heads.
Bodies are offered in polished stainless steel, other
metal alloys, and engineered thermoplastics.
Sensors & instruments
Switches and transmitters for flow, level, pressure,
temperature, and analysis applications are available for
hygienic processes. Pictured left to right are the Type
8055 full bore magflow meter, Type 8138 radar level
transmitter for hygienic processes, and the specialised
glass-free 8201 pH probe that is able to operate
accurately without recalibration for extended periods.
Types 8681 universal control head
The 8681 universal control head is designed to assem-
ble with all commercially available hygienic valves, to
deliver 3-position control. The head incorporates the
super-bright LED position indication, and is rated for
wash-down environments.
Bürkert has an extensive range of innovative products
for the hygienic processing sector, with local and
global success stories including pharmaceutical, dairy,
biotechnology, and other aseptic environments. The
products showcased below are just a small insight into
the world of Bürkert – please contact us to discuss
