World's first proportional solenoid valve with metal diaphragm

Staiger is known in the fluidics world for its reliable proportional solenoid valves with high precision, dynamics and durability.

Now the company has developed a completely new type of proportional valve that balances pressure via a high-precision metal diaphragm. This is Staiger's response to applications with gaseous media for which there are currently no permanently resistant elastomer diaphragm materials. In summary, this pressure-balanced proportional valve with metal diaphragm is primarily used where classic valves with elastomer diaphragms cannot be used due to technical or regulatory requirements.

The proportional valve also has the typical Staiger properties, such as very high precision, high dynamics and a very long service life.

In addition to other technologies, such as piezo, shape memory or linear actuators, which are used as actuators in valves, electromagnets are still the most cost-effective and robust solution in valve technology, also in terms of actuation.
