Travel Counterbalance Valve Assembly - Part of 517-8130 Hydraulic AR
Safety Features
Reverse Prevention System
The motor and mounting group incorporates a built-in reverse-prevention valve that eliminates unintended reverse rotation, preventing operational errors and safety hazards.
One-way valve design ensures hydraulic oil flows in only one direction
Prevents motor reversal due to external forces or hydraulic fluctuations
This safety feature is critical during heavy lifting operations where reverse rotation could cause load drops and serious accidents. The high-flow capacity valve maintains normal motor operation and response speed while providing reliable performance under high hydraulic pressure and frequent use conditions.

Hydraulic Motor Applications
Hydraulic motors are essential components in earthmoving equipment including excavators, backhoe loaders, skid-steer loaders, forklifts, heavy dump trucks, and bulldozers. They power hydraulic cylinders that extend and retract during various operational cycles.
Swing Brake Operation
The swing brake features a multi-disc and plate assembly located in the first stage planetary gear. This spring-applied, hydraulically-released system functions as a parking brake and is not designed for cyclic service braking. Discs and plates are lubricated by the release signal oil for optimal performance and longevity.
