Eaton Control Valve Orifice

Eaton Control Valve Orifice

The Eaton 101619-052 is a constant speed control valve orifice designed for use in Eaton Heavy-Duty Series 2 and Model 72400 hydrostatic piston pumps. Installed within the manual servo control or Remote Electric (RE) control assemblies, often behind the stop/start cartridge, it precisely restricts hydraulic flow to 0.052 inches (1.32 mm). This restriction dampens the control piston's movement, ensuring smooth and controlled changes in pump displacement while preventing erratic operation. It is an essential replacement part for maintaining accurate drum speed control in the hydraulic charge circuits of concrete mixer trucks.

Key Features

• Precision 0.052-inch (1.32 mm) drilled hole diameter for exact hydraulic flow restriction
• Stamped with '52' on the face for quick size identification
• Direct OEM replacement for Eaton manual servo and Remote Electric (RE) control valves
• Dampens control piston movement to ensure smooth pump displacement
