Overview

The MK / FK 50 2/2-way coaxial direct acting valve is part of the CO-AX range of solenoid-operated valves engineered for diverse industrial fluid control tasks. Its coaxial design ensures balanced forces within the valve to provide consistent switching performance regardless of pressure variations. It is suitable for use with a wide range of media, including liquids and gases, even if highly viscous or contaminated. The valve supports both normally closed and normally open configurations, with electrical actuation options at 24 V DC or 230 V AC. It features a solid construction with high protection and insulation ratings, making it suitable for demanding environments. The MK model uses threaded ports while the FK model uses PN 16 flanged connections, both complying with standard industrial interfaces. Operation characteristics such as switching cycles and times allow for efficient process control. Valve specifications may be customized with different materials or accessories based on application needs.
