BMG’s fluid technology department provides and supports various components for fluid technology systems and general industrial applications. These products include valves, hydraulic hoses and accessories, accumulators, cylinders, heat exchangers, hydraulic motors and hydraulic lines, as well as pumps and tank accessories.
Important valves in the BMG product portfolio include InterApp Bianca and Desponia butterfly valves, which are recommended for high efficiency and safe use in demanding industrial flow control applications.
Willie Lamprecht, Manager of the Low Pressure Business Unit of BMG Fluid Technology, said: “The robust butterfly valve is designed to reliably cut off and control corrosive fluids and high-purity applications. The compact butterfly valve has good flow characteristics and low maintenance requirements, even in the most It also has multiple uses in harsh environments to ensure reliable operation.
“Unlike a ball valve, the disc of a butterfly valve is always located in the channel of the flow channel. This means that no matter the position of the valve, it will cause a pressure drop in the flow. Ball valves can only be used for isolation, while butterfly valves can be safely used for isolation and Control flow.
“The advantage of using a quarter-turn butterfly valve over other types is that the simple design of the wafer shape has fewer parts, easy repairs and minimal maintenance.”
BMG’s InterApp Bianca center butterfly valve has a durable PTFE lining and a long service life. It is suitable for corrosive and corrosive fluids and applications that require absolute purity.
These high-performance valves are between DN 32 and DN 900 and are made of ductile iron, carbon steel or stainless steel, which can meet the requirements of all industries. Bianca butterfly valves can be individually configured by BMG to ensure reliable operation and optimal safety in specific applications.
For example, Bianca valves (DN 50-DN 200) complying with FDA requirements have mirror-polished stainless steel discs and high-purity PTFE linings to ensure the safety of active pharmaceutical ingredients. It is recommended to use PFA-coated discs and PTFE-lined Bianca valves for highly corrosive chemical applications.
This series of valves uses specially selected conductive discs and lining materials, and also complies with the explosion-proof directive ATEX 94 / 9EG to ensure safe operation in explosive environments.
The notable features of the Bianca series include high bushing collars, over-molded PFA discs on the shaft, and lifetime pre-loaded safety shaft seals, which ensure a reliable primary and Long-lasting secondary shaft seal operation cycle and high temperature.
The bushing with cavity prevents cold flow on the flange sealing surface, thereby prolonging the service life, while the combination of the PTFE bushing and the PFA overmolded disc ensures low friction, thereby extending the use of the system life. Other features include an external shaft sealing mechanism to protect the valve neck hole and a robust self-lubricating and maintenance-free bushing. Stainless steel valve tags allow full traceability.
BMG stocks various semi-finished components, which can shorten the delivery time even in the large-size Bianca series below DN 900.
The typical application of Bianca butterfly valve is to extract acid and solvent in mining and slurry. Used for additive processing in the oil and gas industry and highly corrosive processes in the steel industry. This series is also suitable for water treatment where minimal impurities need to be avoided.
BMG’s multifunctional InterApp Desponia and Desponia Plus center butterfly valves have a solid body and a solid elastomer lining, designed to safely and reliably regulate liquids and gases in various industries.
Desponia valves are available in sizes from DN 25 to DN 1600 and pressures up to 16 bar, suitable for various industrial applications. This range can provide cast iron and ductile iron valve bodies.
The size of the Desponia Plus series is between DN 25 and DN 600, high pressure applications up to 20 bar, suitable for high temperature or vacuum applications and process automation. This series is suitable for valve bodies made of ductile iron, cast iron or stainless steel.
The liner and disc of this series play a vital role in the butterfly valve lined with elastomer, because they are the only two parts in contact with the fluid. Flucast® lining is suitable for grinding applications and also complies with FDA and EU regulations.
Notable features of this series include an external shaft sealing mechanism to protect the valve neck hole and a long neck design that allows pipe insulation. The fixed gasket can provide blowout protection, and an O-ring is built into the shaft passage, which is part of a reliable shaft sealing system.
The sealing lip on the flange surface provides perfect sealing, and the optimized lining shape ensures precise grip on the body. The square drive disc provides effective and long-lasting torque transmission, and the polished disc edges minimize friction.
Desponia series can ensure safe operation in water treatment process, power generation and harsh chemical treatment applications. These valves can also withstand the operations of the steel industry, where the shut-off valves used to supply gas to molten steel are exposed to harsh conditions. These valves with specially coated discs are also suitable for mining and mud, and are used in extraction processes that require the highest wear resistance and corrosion resistance of the valve.
