The Multiquip 20780-001 is a genuine OEM Hydraulic Pitch Valve Assembly designed for HTX44 and STX55 series hydrostatic ride-on power trowels. As a factory-original component, it is manufactured to the same specifications as the part it replaces, ensuring correct hydraulic response and blade pitch control across compatible machines. Confirmed fitment includes the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55Y6, and STX55J6. Order with confidence knowing Multiquip part number 20780-001 is the direct OEM replacement for these units.
Key Features
- Genuine OEM Hydraulic Precision — Factory-original valve assembly maintains the correct hydraulic pressure and flow characteristics required for accurate blade pitch adjustment on hydrostatic trowels.
- Direct Drop-In Replacement — Engineered to match the original hydraulic circuit connections and mounting configuration, allowing straightforward installation without circuit modifications.
- Broad HTX44 and STX55 Compatibility — Fits HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55Y6, and STX55J6 ride-on trowel models.
- Consistent Pitch Response — A properly functioning pitch valve delivers smooth, repeatable blade angle changes, enabling operators to achieve a uniform surface finish across the full concrete pass.
- Hydraulic System Integrity — Using the correct OEM valve assembly prevents pressure bleed-off and internal leakage that can result from a worn or incorrect replacement, protecting downstream hydraulic components.
The hydraulic pitch valve assembly controls the flow of hydraulic fluid to the blade pitch mechanism on ride-on trowels, allowing the operator to adjust the angle of the trowel blades during operation. Precise pitch control is essential for transitioning between floating and finishing passes — a valve that is worn, stuck, or leaking will cause sluggish or inconsistent blade response, making it difficult to achieve the surface quality the job demands. Replacing a faulty valve assembly with a genuine OEM unit restores full hydraulic authority over blade pitch and protects the broader hydraulic system from the cascading effects of internal pressure loss.
