The Multiquip 22233 HIC Black Pitch Block Valve Assembly is a genuine OEM component designed for hydrostatic ride-on power trowels including the HTX6H, HTXG6DF, STX6H, HTXD6i, and STXD6i. This is a direct OEM replacement sourced from Multiquip, ensuring it meets the exact specifications required for proper blade pitch control on these machines. If you are servicing any of the compatible HTX or STX series trowels, verifying part number 22233 against your machine's parts manual before ordering is always recommended.
Key Features
- Genuine OEM Valve Integrity — Manufactured to Multiquip's original design specifications, ensuring correct flow control and pressure response within the pitch control circuit.
- Direct Replacement for HTX and STX Series — Fits the HTX6H, HTXG6DF, STX6H, HTXD6i, and STXD6i hydrostatic ride-on trowels with no alterations to the hydraulic circuit.
- Critical Blade Pitch Function — This assembly is part of the hydraulic pitch control system; a worn or failing valve directly affects the operator's ability to adjust blade angle and maintain consistent finishing passes.
- Correct Color-Coded Component — The black designation identifies this as the correct variant for the HIC (High Inertia Control) pitch block circuit, preventing mis-installation with other valve assemblies in the system.
- Hydraulic System Safety — Proper valve function is essential for predictable blade response during operation; a degraded valve can cause uncontrolled pitch changes that affect both finish quality and operator control.
The pitch block valve assembly is a hydraulic control component that regulates fluid flow to the blade pitch mechanism on hydrostatic ride-on trowels. It allows the operator to precisely adjust the angle of the finishing blades during operation, which directly determines the pressure applied to the concrete surface and the quality of the finish achieved. When this valve wears or fails, the blades may become unresponsive, drift from the set pitch angle, or behave erratically — compromising both finish quality and safe machine handling.
