Type 2380 – a versatile media-separated valve

Bürkert presents hygienic 2-way bellow control valve for small flow rates

With the Type 2380 Bürkert proves that it is possible to combine standard features with custom options in one advanced valve concept. The compact bellow control valve with a hygienic design for neutral and aggressive media opens up possibilities for numerous applications, including innovative modular solutions.

The new 2-way bellow control valve from Bürkert is a pneumatically actuated process valve with a single action diaphragm actuator. A PTFE bellow ensures the reliable separation of the media from the actuator. The valve is constructed in full compliance with hygienic design requirements and is ideal for demanding control tasks with small flow rates, for which diaphragm valves are not suitable. Applications include food and beverage production, pharmaceuticals and biopharmaceuticals, cosmetics and speciality chemicals. The bellow control valve is available for different port connections from DN6 to DN20 and can be combined with seat sizes from 3 mm to 10 mm. The space-saving drive has a low internal volume, resulting in the compact design and short response times of this valve type. Type 2380 valve features good control action due to the low-friction design, in addition to a linear characteristic. The correction time is generally less than one second.

Numerous combination options

The standard bellow control valve is a new addition to the unique ELEMENT system; in combination with four different Type 869x positioner and process controllers 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. 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 have developed an innovative solution for nitrogen blanketing in liquid storage tanks or fermenters. The block solution consists of a pressure sensor, two bellow 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.
