Offering a high number of electrical and pneumatic connection options, valve terminals can easily adapt to the specific requirements of safety relevant pneumatic actuators. By arranging pneumatic manifolds with different numbers of valves it is possible to realize diverse valve functions. The long service life of over 150 million switching cycles guarantees a long use of the valve system without maintenance or a failure in safety relevant actuators. The electrical connection can either be realized via multipole interface or feldbus.
