Product Overview
The COAX MK 10 NC (Part No. 552374 / Reference VAU22-012963.3.7) is a high-performance coaxial solenoid valve engineered by COAX GmbH, a globally recognized specialist in coaxial valve technology. Unlike conventional poppet or spool valves, this unit utilizes a pressure-balanced coaxial design in which the media flows axially through the valve, directly past the solenoid drive. This construction allows for extremely high flow rates in a compact envelope, with minimal pressure loss and virtually zero dead volume. The MK 10 NC is a normally closed (NC) 2/2-way configuration, meaning the valve remains shut when de-energized and opens upon solenoid actuation. It is designed for demanding industrial process and hydraulic circuits requiring reliable, leak-free shut-off and rapid switching of neutral and slightly aggressive media.

Engineering Features & Advantages
- Precision Performance: The coaxial axial flow path delivers exceptionally high flow capacity with minimal pressure drop, while the pressure-balanced design ensures consistent switching performance regardless of system pressure fluctuations.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust solenoid actuator and media-isolated drive chamber that prevents contamination and extends service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original COAX OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
- Leak-Free Shut-Off: Normally closed configuration provides reliable sealing when de-energized, ideal for safety-critical isolation duties.
- Compact High-Flow Design: Coaxial architecture achieves flow rates typically associated with much larger valves, saving installation space and weight.
Typical Industrial Applications
This COAX MK 10 NC coaxial solenoid valve is widely deployed in plastic injection molding machines for precise hydraulic circuit control, metallurgical presses requiring rapid and leak-free media isolation, construction and marine hydraulic systems operating under high pressure differentials, and CNC machine tools where compact high-flow switching is essential. Its pressure-balanced coaxial design also makes it suitable for general process and pneumatic circuits handling neutral gases and liquids in automated industrial plants.
