The Multiquip 21889 Coil Parker 600211-012Vdc is a genuine OEM hydraulic solenoid coil designed for HTX44K5, HTX44Y4, HTX44Y5, and HTX44K4 hydrostatic ride-on power trowels. This is a direct OEM replacement sourced through Multiquip's authorized parts network, ensuring the correct voltage rating and coil geometry for these machines. Stocking part number 21889 means your HTX44-series trowel stays on the pour without waiting on hard-to-find hydraulic components.
Key Features
- Correct 12V DC Specification — Rated at 12V DC to match the Parker 600211-012Vdc coil spec required by the HTX44 hydraulic system, preventing miswiring and voltage mismatch.
- Genuine OEM Component — Sourced directly from Multiquip, this coil meets the same output and resistance tolerances as the original part installed at the factory.
- Drop-In Hydraulic Valve Compatibility — Engineered to mount directly onto the Parker solenoid valve body already installed in the trowel, requiring no modification to the valve stack or wiring harness.
- Verified HTX44-Series Fitment — Confirmed for HTX44K5, HTX44Y4, HTX44Y5, and HTX44K4 hydrostatic ride-on trowels — cross-reference your model code before ordering.
- Hydraulic Control Integrity — A functioning coil maintains precise solenoid actuation across the hydraulic circuit; a failed coil causes loss of blade pitch or drive control, taking the trowel out of service mid-finish.
- Electrical Safety Compliance — Using the correct OEM-rated coil on a hydraulic solenoid prevents overheating, coil burnout, and potential damage to downstream valve components in the hydraulic system.
A hydraulic solenoid coil converts an electrical signal into a magnetic field that shifts the valve spool inside a hydraulic solenoid valve, controlling the flow of hydraulic fluid to a specific circuit. On HTX44-series hydrostatic ride-on trowels, these solenoid valves govern critical functions such as blade pitch adjustment and machine drive. When the coil fails — whether from voltage spike, heat fatigue, or normal wear — the valve spool stops responding, causing the affected hydraulic circuit to lose control response entirely. Replacing the coil with the correct OEM-rated Parker 600211-012Vdc unit restores full solenoid function and brings the hydraulic circuit back into reliable operation.
