Series KN and KN High Flow: Compact Power in Motion Control

When it comes to miniaturized fluid control, performance, precision, and reliability are essential. The Series KN and KN High Flow solenoid valves deliver exactly that. These direct acting 3/2-way valves, available in Normally Closed (NC), Normally Open (NO), and Universal (UNI) configurations, are engineered to meet the dynamic needs of modern industrial and scientific environments.

Key Features at a Glance:

• Direct acting poppet type mechanism for quick and reliable switching
• Low energy consumption, making them ideal for battery-operated or energy-sensitive systems
• Compact design allows for space-saving installations in dense assemblies
• High flow performance available in the KN High Flow version
• ISO 15218 interface compatibility ensures standardized and flexible integration
• Oxygen-compatible versions available, expanding their range of safe applications

Built for Demanding Applications

From lab automation to semiconductor manufacturing, the Series KN is designed for critical use cases where precision and response time matter. With a response time of less than 10 ms, these valves provide near-instantaneous actuation, ensuring smooth operation in high-speed systems.

Technical Excellence

• Orifice diameter: 0.65 to 1.1 mm
• Flow coefficient (kv): 0.15 to 0.39 l/min
• Operating pressure: 0 to 3…7 bar
• emperature range: 0 to 50°C
• Fluid compatibility: Filtered compressed air or inert gases, compliant with ISO 8573-1:2010 [3:4:3]

Electrical Efficiency

With power consumption as low as 0.25 W (holding) and a duty cycle of 100% ED, these valves are designed for continuous operation. The Series KN supports 5 to 24 V DC inputs and offers flexibility with other voltages on demand.

• Voltage tolerance: ±10%
• Electrical connection: Connector mod. 121-8...
• Protection class: IP50

Materials Built to Last

• Valve body: Durable PBT
• Seals: NBR and FKM for broad chemical compatibility
• Internal parts: Corrosion-resistant stainless steel

Designed for Flexibility

With monostable manual override and installation in any position, the Series KN ensures ease of maintenance and integration, even in tight or unconventional layouts.

Whether you’re optimizing a precision test rig or automating a compact production system, the Series KN and KN High Flow solenoid valves offer a unique combination of efficiency, reliability, and high performance in a miniature form factor. Backed by ISO standards and adaptable across industries, these valves are a powerful choice for demanding applications.
