Sourced through DHS Equipment, the EM11431 is the correct specification part to keep your ride-on trowel operating as intended.

Key Features

• Genuine OEM Construction — Manufactured to the exact material and dimensional tolerances of the original valve, ensuring consistent hydraulic or fuel circuit behavior specific to this trowel platform.
• Direct Drop-In Replacement — Engineered to match the original mounting configuration and port sizing on supported trowel models, allowing straightforward installation without reworking fittings or lines.
• Broad Ride-On Trowel Compatibility — Confirmed fitment across HTX44, HTN, and HHN series Whiteman ride-on power trowels, as well as EHHNK5 and HTNS5S-2 international variants.
• Maintains Proper Flow Control — A correctly functioning DNO valve ensures the intended circuit operates at the right pressure and flow rate, supporting smooth trowel blade engagement and drive response.
• Critical Hydraulic Circuit Integrity — A worn or failed valve can cause erratic machine response or circuit bypass; replacing with an OEM-spec part restores intended system behavior and operator control.

A DNO valve is a directional or normally-open control valve used within a hydraulic or fluid circuit to manage the flow and direction of fluid under pressure. In a ride-on power trowel, this type of valve plays a role in controlling blade pitch adjustment or drive functions by opening and closing fluid pathways on command. When the valve wears, sticks, or fails, operators may experience loss of blade control, sluggish response, or uncontrolled movement — making timely replacement essential to safe and productive finishing work.
