Unique RV-ST

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.
