Available — Atlantechdrives provides you the UF3-230VAC, a high-durability electromagnetic solenoid coil engineered by Kuhnke for precision 230V AC valve actuation in industrial control systems. This component is essential for converting electrical signals into mechanical force to shift pneumatic or hydraulic valve spools reliably.
What Is the UF3-230VAC?
The UF3-230VAC is a professional-grade AC-rated solenoid coil from the Kuhnke UF-series, specifically designed for 230V alternating current operation. This coil is characterized by its high-quality copper windings and advanced resin encapsulation, which protects the sensitive electrical components from industrial contaminants, moisture, and thermal stress. The UF series is renowned for its volumetric efficiency and low power consumption, making it a preferred choice for engineers looking to optimize cabinet thermal management. When energized, the UF3-230VAC generates a stable magnetic field that decisively pulls the valve armature, ensuring consistent switching performance even under high-cycle industrial operations. Its design includes a standardized industrial interface for rapid electrical connection and is fully rated for 100% continuous duty (ED), allowing it to remain energized indefinitely without risk of overheating or performance degradation. This reliability makes the UF3-230VAC a staple in manufacturing environments where downtime must be minimized, particularly in Europe and other regions where 230VAC is the standard control voltage.

Applications and System Architecture
The UF3-230VAC is predominantly used in the control panels of automated assembly lines, industrial HVAC systems, and water treatment facilities. In a standard architecture, it serves as the final actuator for directional control valves, managed by a 230V control branch of the PLC or a master control relay. Its use of alternating current is particularly advantageous in facilities with long cable runs where DC voltage drop could be an issue. The coil’s robust construction ensures that it can withstand the electrical noise and vibration common in proximity to large electric motors and drives. By utilizing genuine Kuhnke UF series coils, system integrators ensure perfect mechanical alignment with the valve armature, preventing the buzzing and premature wear often associated with generic replacement parts.
Maintenance Tips
To ensure the longest possible life for your UF3-230VAC, never energize the coil while it is removed from the valve stem; without the iron core to provide inductance, the coil will rapidly overheat and burn out almost instantly. We recommend periodically inspecting the electrical pins for signs of oxidation or arcing, especially in humid industrial settings. Always verify that the electrical plug gasket is properly seated to maintain the IP65 protection rating. If the valve is located in an area with high-frequency voltage spikes, consider using a connector with integrated surge protection or an RC element to shield the coil windings from transient electrical stress.
Frequently Asked Questions
Q: Can I use the UF3-230VAC on a 230V DC circuit?
A: No, this coil is specifically wound for alternating current (AC). Using it with DC will cause a massive overcurrent that will destroy the coil almost instantly due to the lack of AC impedance.
Q: Is the UF3-230VAC interchangeable with other Kuhnke coil series?
A: While many Kuhnke coils look similar, the UF series has specific internal dimensions; always verify the valve stem diameter and series compatibility before swapping modules to ensure proper fit.
This 230VAC coil is fully compatible with the UF3-24VDC mounting interface, both belonging to the Kuhnke UF3 coil family and interchangeable on the same 76-series valve body for installations requiring different supply voltages.
