Product Overview
The COAX MKF-1 15 PC NC is a high-performance coaxial solenoid valve engineered by COAX (a Müller Coax brand), a globally recognized manufacturer of precision coaxial valve technology. Unlike conventional poppet or spool valves, this unit utilizes a coaxial working principle in which the actuating piston and the sealing element are arranged on a single common axis, enabling the medium to flow directly through the valve in a straight, unobstructed path. The “NC” designation indicates a normally closed configuration, meaning the valve remains sealed when de-energized and opens only upon solenoid energization. The “15” refers to the nominal bore size, and the “PC” variant denotes a pressure-compensated design that maintains reliable switching performance across a wide differential pressure range. This valve is designed for precise control of neutral and slightly aggressive gaseous and liquid media in demanding industrial process circuits, delivering bubble-tight sealing, high flow capacity, and exceptionally long service life.

Engineering Features & Advantages
- Precision Performance: The coaxial piston design provides a straight-through flow path with minimal pressure drop, delivering high flow rates and fast, repeatable switching response for accurate process control.
- Bubble-Tight Sealing: The pressure-compensated (PC) sealing geometry ensures zero-leakage shut-off even at high differential pressures, making the valve suitable for critical media isolation.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust solenoid construction and wear-resistant sealing materials for extended cycle life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original COAX MKF-1 series OEM standards, ensuring drop-in interchangeability.
Typical Industrial Applications
The COAX MKF-1 15 PC NC coaxial solenoid valve is widely deployed in plastic injection molding machines for precise media control, metallurgical presses and furnace systems requiring reliable high-pressure shut-off, construction and marine hydraulic circuits, and CNC machine tools where fast, leak-free valve actuation is essential. Its pressure-compensated coaxial design also suits general industrial process and pneumatic control loops handling neutral gases and liquids.
