RIEGER LCV single-seat valves can be found in systems in the food industry. They combine the advantages of the cavity-free valve housing with the concept of the maintenance-free welded valve drive. The spring-loaded drive can be used both as spring-closing and spring-opening by simply turning it.
Angle valves and diverter valves are based on the same housings. They can be combined in a variety of ways, thus reducing spare parts inventory. In daily use, LCV valves guarantee high flexibility within the series and the perfect application for your liquid products.
