Burkert presents hygienic two-way bellows control valve for small flow rates

The new two-way bellows control valve from Bürkert is a pneumatically actuated process valve with a single action membrane drive.

A PTFE bellows ensures the reliable separation of the media from the drive.

The valve is constructed in full compliance with hygienic design requirements and is ideal for demanding control tasks with small flow rates, for which membrane valves are not suitable.

Applications include food and beverage production, pharmaceuticals and biopharmaceuticals, cosmetics and speciality chemicals.

The bellows control valve is available in diameters from DN6 to DN20 and can be combined with seat diameters from 3–10mm.

The space-saving drive has a low internal volume, resulting in the compact design and short response times of this valve type.

Type 2380 valves feature good control action due to the low-friction design, in addition to a linear characteristic curve.

The correction time is generally less than one second.

The standard bellows control valve is a new addition to the unique ELEMENT system; in combination with four different Type 869x positioning and process valves of the Element series, as well as different connections (sleeve, clamp and welded connection) and a large choice of bodies and block solutions, it enables creation of a modular system with numerous options.

The Type 2380 is designed for control functions such as the control of gases in fermentation processes and bioreactors, as well as dosing applications with small flow rates.

On the basis of this valve type the fluidics experts at Bürkert has developed an innovative solution for overlying liquid nitrogen in liquid storage tanks or fermenters.

The block solution consists of a pressure sensor, two bellows control valves and two Element positioners.

As opposed to the previous control concepts available on the market, this solution reliably prevents contamination, foaming and cleaning problems common in fermenters.
