Valve body variants

We assist you to choose the correct valve for your application. Starting with the body you can select valves to control slurries, steam, aggressive liquids and materials which must remain pure. We offer four main methods for controlling fluids from our world renowned angle seat pattern to a range of quarter turn solutions. The choice is yours

2. Globe

2.1 Globe Continuous Control Valves

A winning solution for many demanding control applications, the globe control valve is the standard in many industries. Bürkert’s idea is to take the standard to a new level in an compact, light weight envelope. These valves exhibit effective valve characteristics for continuous variation of the flow as a function of the parabolic plug position guided by a linear low friction stem.

Stainless steel or PTFE seals to give either Class IV or Class VI shutoff and each body size has a range of control plugs and corresponding replaceable seats for perfect sizing of any throttling application. State of the art online sizing tools make valve sizing easy and can even predict life-time considering caviation, flashing, choking and flow speed.

Flow Characteristics

3 kVs values per body size as standard feature with seat reductions the optimum flow characteristics for the application can be selected.

3. Diaphragm

3.1 Diaphragm Continuous Control Valves

The weir pattern is quite unique in its ability to control very pure substances where a minimum of wetted materials and dead volumes are absolutely required although using a diaphragm valve without proper understanding of its inherent flow profile would present difficulties.

With the help of our range of very smart positioning software our diaphragm technology can be made to respond to the challenge of accurate and reliable flow and pressure control.

Our customers get all the resistance and drain-ability advantages of the weir pattern valve mixed with accurate control characteristics.

For the precise control of small volumes the bellow control valve (Type 2380) the perfect supplement for the diaphragm control valves.

A PTFE bellow eliminates contamination risks is robust, suitable for any media and comes with all necessary approvals. The stainless steel body is easy to clean and available in many configurations.

3.2 Diaphragm On/Off Valves

Available in a wide range of plastic and metallic materials, this isolated and media resistant design has an excellent reputation for versatility and reliability in both aseptic and in industrial applications where corrosive, pure or abrasive media are controlled.

The diaphragm is the key performance component within a modular architecture and is relied on to provide leaktight shutoff to the downstream side of the weir, to atmosphere and to the actuator mechanism.

Standard and customized diaphragm materials are offered for requirements of temperature, chemical resistance or specific USP certifications.

We continuously develop our understanding of all aspects of polymer and rubber technology, diaphragm design and lean production techniques.

The bodies can be provided to meet many surface finish requirements and usually are accompanied by a host of quality and industry specific certifications or approvals.

The weir pattern of the valve has a very favorable flow characteristic and is also drainable and abrasion resistant. We deliver cast and forged stainless steel, hydro-formed bodies and plastics with many different process connections to a wide variety of customers who expect their particular solution works every time.
