Direct acting solenoid valves Series K8 – K8X
2/2-way – Normally Closed (NC) and Normally Open (NO)
3/2-way – Normally Closed (NC) and Normally Open (NO)
3/2-way – Universal (UNI)
3/2-way – Normally Closed (NC) and Normally Open (NO)
3/2-way – Universal (UNI)
Thanks to their particular design these valves can be used in applications where very compact solutions are required as well as high performances.
Series K8 is used to control actuators or very small devices and it is suitable for portable equipments thanks to low power consumption, reduced weight and dimensions.
The universal (UNI) version enables to mix two different gaseous fluids or to select the path of the gaseous fluid in the pneumatic circuit.
