K8 Series Solenoid Valves: Compact Precision for Demanding Applications

The K8 and K8X Series of direct acting solenoid valves represent a cutting-edge solution for pneumatic systems where compactness, efficiency, and reliability are essential. Available in 2/2- and 3/2-way configurations, both Normally Closed (NC) and Normally Open (NO), as well as a Universal (UNI) version, the K8 Series offers unmatched flexibility for controlling actuators or small pneumatic devices.

With their ultra-compact design and lightweight construction, K8 valves are ideal for integration into portable equipment and applications where space is at a premium. Their low power consumption (just 0.6 W) makes them especially suited for battery-operated systems, without compromising on response time or reliability.

The direct acting poppet type operation ensures precise control with fast response times—<10 ms for both ON and OFF cycles. The universal (UNI) configuration allows engineers to mix gases or reroute the flow path, making the K8 Series a versatile choice for a wide variety of pneumatic circuit designs.
