Burkert safety shutdown valves

Bürkert has expanded its Type 8640 valve island and the Type 8644 automation system to include new versions of the Type 6524 and 6525 pneumatic valves for safety-related shutdown. These valves enable the safe shutdown of processes up to performance level c.

In conformity with the Machinery Directive, the valves are designed for all applications with special requirements for process safety. This includes the food and beverage industry, pharmaceuticals and chemicals, as well as industrial water systems. The components are installed in emergency systems for immediate process shutdown for example, as well as for increased safety in processes involving high temperatures and hot vapours.

In general, Bürkert valve islands and automation systems are suitable for use in many different types of hygienic process environments due to the integrated process safety features of the Type 8640 valve island and the Type 8644 automation system. Check valves integrated in the exhaust air duct guarantee that in the event that all actuators are shut down simultaneously during a disturbance in the system, no back pressure can accumulate in a valve block, which could result in unwanted switching of a process valve, with serious consequences for the process. A hot-swap function allows replacement of faulty valves even during operation, without the risk of loss of air pressure on the entire valve block. The combination of a valve terminal or automation system with the AirLINE Quick adapter provides an especially compact system solution for even more flexibility in a smaller space.
