The Multiquip 20780 is a genuine OEM Hydraulic Pitch Valve Assembly designed for HTX44 and STX55 series hydrostatic ride-on power trowels. This is a direct OEM replacement sourced from Multiquip, ensuring the part meets the original engineering specifications for the Sauer hydraulic pitch control system used across HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, and STX55Y6 machines. Choosing a genuine OEM component means you get the correct valve geometry, porting, and pressure tolerances required for precise blade pitch response. DHS Equipment stocks the Multiquip 20780 so you can get your trowel back on the slab without delay.
Key Features
- Genuine OEM Hydraulic Precision — Built to exact Sauer system specifications, maintaining the correct flow rate and pressure response critical for accurate blade pitch control.
- Direct-Fit Replacement — Engineered to install in the same hydraulic circuit position as the original valve assembly, with matching port configuration and mounting interface.
- Broad HTX and STX Series Coverage — Confirmed fitment for HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, and STX55Y6 hydrostatic ride-on power trowels.
- Consistent Blade Pitch Performance — A properly functioning hydraulic pitch valve allows operators to dial in blade angle with precision across the full finishing pass; a worn or failing valve causes erratic pitch response and uneven surface finish.
- Hydraulic System Integrity — As a fluid control component in the pitch circuit, correct valve seating and actuation are essential to prevent pressure loss and unintended blade movement during operation.
The hydraulic pitch valve assembly controls the flow of hydraulic fluid to the pitch adjustment mechanism on hydrostatic ride-on power trowels. By regulating pressure and direction within the pitch circuit, the valve allows the operator to precisely adjust the blade angle during finishing, which directly affects surface texture and flatness. When this valve wears or fails, symptoms typically include sluggish blade response, inconsistent pitch across the rotor, or a complete loss of pitch control — all of which compromise finish quality and can force an early stop to the pour cycle.
