Key Features

• Genuine OEM Spring Rate: — Manufactured to the precise tension specification required for correct collet valve actuation in the DLW400ES series.
• Direct-Fit Replacement: — Dimensionally matched to the original component for straightforward installation with no alteration to surrounding hardware.
• Confirmed Fitment: — Compatible with DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder/generator models.
• Sustained Valve Integrity: — A correctly tensioned collet valve spring maintains consistent seating pressure, supporting stable fuel or fluid control throughout operation.
• Fuel System Safety Relevance: — Springs in collet valve assemblies are critical to maintaining a sealed fuel circuit; a fatigued or broken spring can result in improper valve seating and fuel delivery issues.

The collet valve spring applies consistent return pressure to the collet valve, keeping it properly seated when closed and allowing controlled actuation when the valve is operated. In a welder/generator application, this spring is part of the fuel system circuit and ensures the valve responds correctly under normal operating conditions. When the spring weakens, cracks, or loses its rated tension, the valve may fail to seat fully, leading to irregular fuel flow, difficult starting, or potential leakage within the fuel system.
