Multiquip 42611-1 Pressure Relief Valve 300 Bar

The Multiquip 42611-1 is a genuine OEM Pressure Relief Valve 300 Bar designed for HTX6H and STX6H hydrostatic ride-on power trowels. As a factory-sourced component, it meets the exact pressure specification of the original part, ensuring the hydraulic system operates within its designed parameters. This valve is confirmed to fit the HTX6H heavy-duty hydrostatic series and the STX6H super-sized hydrostatic series, making it a direct replacement for worn or failed units on those machines.

Key Features

• Factory-Rated 300 Bar Pressure Spec — Calibrated to the exact relief pressure required by the HTX6H and STX6H hydraulic circuits, preventing over-pressurization without sacrificing system output.
• Genuine OEM Component — Sourced directly from Multiquip, this valve matches the original part in thread pitch, port size, and cracking pressure — no rework needed to install.
• Confirmed Fitment for HTX6H and STX6H — Verified for the heavy-duty hydrostatic and super-sized hydrostatic ride-on trowel series, so you can order with confidence.
• Protects Hydraulic System Integrity — A correctly functioning relief valve prevents excess pressure from damaging pumps, motors, and hoses throughout the trowel's hydraulic circuit.
• Hydraulic Safety Compliance — In a high-pressure hydrostatic drive system, a properly rated relief valve is a critical safety component; using an incorrect or worn valve risks uncontrolled pressure buildup and system failure.

A pressure relief valve is a hydraulic safety and regulation component that limits the maximum pressure within a hydraulic circuit. In the HTX6H and STX6H ride-on trowels, the hydraulic system controls both blade pitch and machine drive, so maintaining correct pressure is essential to smooth, predictable operation. When a relief valve wears out or fails to open at the correct threshold, pressure can spike beyond safe limits — leading to pump damage, burst hoses, or loss of drive control on the trowel.
