Продукция, изготовленная шведской Alfa Laval компанией, подходит для использования в пищевой, химической, фармацевтической, горнообрабатывающей и нефтяной промышленности.Преимуществом товара является длительный срок службы без необходимости осуществления регулярного обслуживания, а также его первоклассное качество и надежность. With an integrated IP converter and push-and-play setup, the Unique RV-ST regulating valve meets the highest process demands for hygiene and safety. Built on the Unique SSV platform, it is ideal for high-volume sanitary liquid processing applications. Hygienic corrosion-free regulating valve The Alfa Laval Unique RV-ST is an intelligent hygienic regulating valve that safely and effectively controls process flows with Kv values between 9 and 246 m3/hour. It is designed for a wide range of fluid handling duties, such as metering, blending, weighing and filling system duties, in the food and beverage, brewery, biotech and pharmaceutical and chemicals industries. Corrosion-free features, such as tapered stainless steel stems, ensure product safety according to EHEDG (European Hygienic Engineering & Design Group) guidelines. Advanced electro-pneumatic controller The Unique RV-ST regulating valve comes with an advanced electro-pneumatic controller with an integrated IP converter. This offers superior control of product flow by combining different pressure drops and stroke lengths. It also features a contact-free analog position sensor, which measures the position of the valve spindle, and a standard Profibus DP-V1 or optional DeviceNet communications interface. Analogue or binary feedback is available as options. Easy push-and-play regulating valve setup With a push of a button, the Alfa Laval Unique RV-ST regulating valve automatically calibrates itself so that it is fully operational. Reliable, easy to maintain Built on the proven Unique SSV (Single Seat Valve) platform, which has an installed base of more than one million valves, the Alfa Laval Unique RV-ST UltraPure offers the same reliability, safety and ease of maintenance. Its offers protection class IP65 and IP67 for tough process environments. A regulating valve with maximum flexibility It uses the same few moveable components, spare parts and maintenance tools and procedures as Alfa Laval Unique SSV valves. Using the upgrade kit available, it is possible to upgrade older regulating valves with the new control unit. The new control unit also supports rebuild of the actuator from NC (Normally Closed) to NO (Normally Open) and vice versa. Product Benefits

The essentials for future foods Alfa Laval's hygienic equipment combines high performance with gentle handling to preserve sensitive ingredients. Food logic Каталог продукции Онлайн-версия каталога «Close at hand» Найти изделие Альфа Лаваль Construction The Alfa Laval Unique RV-ST regulating valve with integrated IP converter is a second-generation single-seat valve. It features:
  • Broad selection of stainless steel tapered valve stems
  • Unique actuator with electro-pneumatic process controller for precise control of product flow
  • Rugged, long-lasting plastic stem bushings that eliminate metal-to-metal galling
  • Standard EPDM plug seal used by the entire Unique valve series
The stems are threaded to the actuator shaft, which eliminates the coupling between the stem and the actuator, thereby ensuring proper alignment. Bushings at end of the actuator cylinder support the stem and ensure perfect alignment. Operating principle The Alfa Laval Unique RV-ST regulating valve can be controlled from a remote location by means of a digital electro-pneumatic process controller. The control unit comes in two versions: with or without display. It has an analogue 4-20 mA communication interface and is protected according to IP66 and IP67. Options
  • Male parts or clamp liners in accordance with required standard
  • Product wetted seals in HNBR or FPM
  • Maintainable actuator
  • External surface finish blasted
  • Optional plug seal: HNBR or FPM
