Description

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.

How it works 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
