Composed of a broad range of multiport composite valves with service flow rates up to 35m³/hr and advanced professional controllers, Siata offers a full range of solutions that simplify the whole operating process on water treatment plants.

The key concept of Siata is to offer valves that can be fitted with almost any controllers depending on the customers needs, and giving several hundred of individual configurations. Pentair engineers work closely with customers to develop personalised solutions to their specific application. The result is a unique combination of valves and related controllers for years of reliable and trouble free service.
