VSNC valves are pilot valves for single- and double-acting quarter turn and linear actuators with a port pattern in accordance with VDI/VDE 3845, such as DRD/DRE, DAPS, DFPB. DLP. Mounting on actuators without a NAMUR interface, e.g. diaphragm actuators, is also possible thanks to appropriate accessories such as a connection plate kit. They are designed for the requirements of process automation. Mechanical springs (singlesolenoid valves) ensure secure switching to the initial position in the event of a power failure.
