M&S spring-loaded safety valves are TÜV component-tested valves that are used to protect hygienic pressure-bearing systems, such as pressure vessels or piping systems, in the event of an impermissible increase in pressure.
M&S vacuum valves are used for vacuum protection in hygienic containers, apparatus and machines.
M&S non-return valves are used in process engineering plants to prevent the flow reversal of fluids (liquids or gases) in pipelines.
For example, they prevent the liquid column in a riser pipe from flowing back if a feed pump fails.
M&S sampling valves are used to take samples of liquids from containers or pipelines. Depending on the purpose of sampling, different sampling systems are used.
