Product Overview
The Wandfluh SIS45V solenoid coil (part reference 179118075) is a genuine replacement coil assembly engineered for Wandfluh directional, proportional, and pressure control valves used in industrial hydraulic systems. As an electromagnetic actuator, the coil converts an electrical control signal into a precisely guided magnetic force that shifts the valve spool or poppet, thereby directing, throttling, or blocking hydraulic flow within the circuit. Manufactured by Wandfluh AG, a recognized Swiss specialist in hydraulic valves and control electronics, this coil is designed as a direct-fit spare for maintenance, retrofit, and repair programs where valve uptime and repeatable switching behavior are critical. It is supplied as a standalone electrical accessory and does not include the valve body, spool, or hydraulic housing.

Engineering Features & Advantages
- Precision Magnetic Actuation: The coil winding and core geometry are matched to Wandfluh valve spool dynamics, delivering consistent pull-in and drop-out force for repeatable switching and stable proportional control.
- Thermal Endurance: Constructed with high-temperature insulation materials and a robust encapsulation, allowing continuous energization without premature winding degradation.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, including vibration, contamination-prone environments, and fluctuating supply voltages.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, enabling drop-in replacement without modification of the valve body or electrical harness.
- Serviceability: Supplied as an individual spare part, allowing targeted replacement of a failed coil while retaining the existing valve assembly and hydraulic circuit.
Typical Industrial Applications
This Wandfluh solenoid coil is used wherever Wandfluh solenoid-actuated valves control hydraulic flow and pressure, including plastic injection molding machines, metallurgical and forming presses, CNC machine tools and machining centers, construction and marine hydraulic systems, and general industrial power units requiring reliable directional or proportional valve actuation.
