The Multiquip 22177 is a genuine OEM Pressure Relief Valve 300 Bar designed for STX and HTX series hydrostatic ride-on power trowels. As a direct OEM replacement sourced from Multiquip, this valve is manufactured to the same specifications as the original component, ensuring consistent hydraulic system behavior across the machines it serves. Confirmed fitment includes the STXD6i, HTXG6DF, and HTXD6i models.
Key Features
- OEM-Calibrated Pressure Rating — Set to the precise 300 Bar threshold required by the hydraulic circuit, preventing over-pressurization without sacrificing blade and drive response.
- Direct-Mount Replacement — Engineered to match the original valve's port size, thread specification, and body dimensions for a straightforward swap into the existing hydraulic circuit.
- Confirmed STX and HTX Fitment — Verified for STXD6i, HTXG6DF, and HTXD6i hydrostatic ride-on trowels, keeping the right part matched to the right machine.
- Hydraulic System Integrity — A correctly functioning pressure relief valve protects hydraulic pumps, motors, and hoses from damaging pressure spikes that can cause costly downstream failures.
- Operator Safety Compliance — Pressure relief valves are a critical safety component in hydraulic systems; using the correctly rated OEM part helps ensure the system operates within its designed pressure limits.
A pressure relief valve regulates the maximum operating pressure within a hydraulic system by diverting excess fluid back to the reservoir when pressure exceeds the set limit. On hydrostatic ride-on trowels like the STX and HTX series, this valve protects the hydraulic drive and blade-pitch control circuits from sudden pressure surges caused by load changes or operator inputs. When the valve wears, sticks, or loses its calibrated setting, the result can range from sluggish blade response to catastrophic pump or motor damage — making timely replacement with the correct-specification part essential.
