ESI Technologies Group
LESER’s Clean Service safety valves are engineered for industries demanding the highest aseptic standards, including food processing and pharmaceuticals. Designed for superior cleanability, they support CIP (Clean-in-Place), SIP (Sterilization-in-Place), and COP (Clean-Out-of-Place) processes, ensuring optimal hygiene and minimal contamination risk.
Type 483 Designed for small to medium capacity; Type 483 has optimised Clean Service properties for applications requiring clamp connections. Type 483 is applicable in all Clean Service areas (e. g. bottle filling machines, fermenters).
Type 484 Designed for small to medium capacity; Type 484 meets the highest sanitary requirements for high purity applications, e. g. fermentors. The design incorporates a dead space free vessel connection, which is directly welded into the vessel wall and allows maximum cleanability of the valve inlet.
Type 485 Designed for small to medium capacity; Type 485 meets the highest sanitary requirements for high purity applications, e. g. fermentors. The design incorporates a dead space free pipe connection, which is directly welded into the pipework and allows maximum cleanability of the valve inlet. Type 485 can be used in applications where a direct vessel connection used by the Type 484 is not possible, e. g. glass vessels.
Type 481 Designed for small capacity; Type 481 offers protection for installations in which Clean Service properties are required only at the valve inlet, e.g. protection of gas systems for the bottling of beverages.
Type 488 Designed for high capacity; Type 488 provides Clean Service properties for applications requiring larger capacities. Type 488 is applicable in large plants, breweries and the beverage industry.
