BMG Interapp Desponia & Bianca butterfly valves VALVES
BMG’s Fluid Technology division supplies and supports an extensive range of components for fluid technology systems and general industrial applications.
These products include valves, hydraulic hoses and fittings, accumulators, cylinders, heat exchangers, hydraulic motors and hydraulic plumbing, as well as pumps and reservoir accessories. Important valves in BMG’s portfolio include InterApp Bianca and Desponia butterfly valves, which are recommended for high efficiency and safe use in demanding industrial flow control applications. “Robust butterfly valves are designed for dependable shut-off and control of corrosive fluids, as well as highpurity applications,” says Willie Lamprecht, BMG’s Business Unit Manager, Fluid Technology Low Pressure. “Compact butterfly valves, with good flow characteristics and low maintenance requirements, are extremely versatile and ensure dependable operation, even in the toughest environments. “Unlike a ball valve, the discs of butterfly valves are always present in the passageway within the flow. This means a pressure drop is induced in the flow, regardless of the position of the valve. Ball valves should only be used for isolation, whereas butterfly valves can be safely used for isolation and control of flow. “An advantage of using quarter turn butterfly valves rather than any other type of valve, is the simple, wafer-shaped design, with fewer parts, for easy repair and minimal maintenance.” BMG’s InterApp Bianca centric butterfly valves, with durable PTFE liners, are built for long service-life and are suitable for aggressive and corrosive fluids and for applications where absolute purity is essential. These high-performance valves, which are available in sizes between DN 32 and DN 900, are manufactured with a ductile iron, carbon steel or Stainless Steel body, to suit the requirements of all industries.

be individually configured by BMG to ensure dependable operation and optimum safety in specific applications. For example, FDA compliant Bianca valves (DN 50 – DN 200) with mirror-polished Stainless Steel discs and highpurity PTFE liners, ensure safety for the production of active pharmaceutical ingredients. Bianca valves with PFA-coated discs and PTFE liners are recommended for use in highly corrosive, chemical applications. Valves in this range, with specially-selected conductive disc and liner materials, also conform with the explosion protection directive ATEX 94/9EG, ensuring safe operation in explosive environments. Notable features of the Bianca series include a high liner collar, a PFA disc over-moulding on the shaft, as well as a life-time pre-loaded safety shaft sealing, ensure reliable primary and long-lasting secondary shaft sealing, even for
