Shut-off valve, AVR D AE, GEA AWP

Possible Applications

This shut-off valve is primarily utilized in industrial refrigeration systems and large-scale ammonia cooling plants where reliable isolation of refrigerant circuits is critical for maintenance and safety. Its straightway design and butt welding configuration make it ideal for permanent integration into high-pressure piping networks found in cold storage warehouses, food processing facilities, and chemical manufacturing plants. The stem-sealing mechanism with a spring-loaded PTFE ring ensures long-term leak-tight performance under fluctuating thermal conditions, which is essential for preventing the escape of hazardous refrigerants in complex cooling loops. By providing a robust, low-maintenance solution for flow control, this valve effectively supports the operational integrity of liquid line and suction line assemblies in demanding thermal management environments.
