Throttle valve Type RIA

RIA is specially designed for use for flue and exhaust gases up to 1100°C. Depending on specifications, we can supply RIA in various, ready-made configurations, or we can adapt it to precisely suit your specific needs. RIA has an Integrated ISO interface. This allows for direct mounting without the need for an additional console – which means the RIA can be automated quickly and easily later on. RIA is very robust, durable and requires little maintenance. With its safe and proven design, RIA guarantees high system availability even under extreme conditions.
