Description
Kuhnway Queen M20 Replacement Solenoid Coil – 20.3mm Bore
The Kuhnway Queen M20 is a replacement solenoid coil designed for compatible Kuhnway direct acting bronze steam solenoid valves, including the MKS Series.
Featuring a 20.3mm coil bore, 49mm body height and Class H insulation, this heavy-duty replacement coil is suitable for restoring electrical operation to compatible industrial steam solenoid valves without replacing the complete valve assembly.
Available in 110V AC and 230V AC configurations, the M20 coil is designed for continuous-duty solenoid valve applications and provides IP65 ingress protection when correctly fitted with a suitable electrical connector.
Kuhnway Steam Solenoid Valve Compatibility
The M20 coil is suitable for compatible Kuhnway Queen MKS Series direct acting bronze steam solenoid valves, including selected 11/4" to 2" models.
Before ordering, confirm the existing coil dimensions, voltage, mounting arrangement and electrical connection.
The M20 designation and coil bore dimensions are particularly important when identifying a replacement coil.
Coil Dimensions & Mounting
The M20 replacement coil has the following dimensions:
- Main Coil Bore: 20.3mm
- Mounting Plate Hole: 10mm
- Coil Height: 49mm
- Coil Width: 60mm
- Coil Length: 42mm / 57.5mm
The stepped bore and mounting arrangement should be checked against the original solenoid valve operator to ensure correct installation.
Electrical Specifications
The Kuhnway Queen M20 solenoid coil is available with the following electrical configurations:
- 110V AC, 50/60Hz
- 230V AC, 50/60Hz
Additional voltage versions may be available upon request.
Electrical performance:
- DC Power Consumption: 19W
- AC Inrush Power: 35VA
- AC Holding Power: 26VA
- Insulation Class: H (180°C)
- Ingress Protection: IP65 with suitable connector
- Electrical Connection: DIN 43650 Form A
The Class H insulation system is designed for elevated-temperature electrical applications, although the permitted ambient temperature depends on the complete valve and coil assembly.
Replacement & Installation
Replacing a failed solenoid coil can restore operation without requiring replacement of the complete steam solenoid valve.
Before installation:
- Confirm the correct supply voltage.
- Check the coil bore and mounting dimensions.
- Inspect the solenoid armature and core tube.
- Ensure the replacement coil is securely retained.
- Fit the correct electrical connector and seal.
The coil must only be energised when correctly fitted to its compatible solenoid operator.
