These valves are a combination of a pilot operated relief valve and a solenoid operated
directional valve. Piping between the two is eliminated as the solenoid valve is directly
mounted on the relief valve and connected with the relief valve vent. Pump pressure
may be unloaded remotely by an electrical signal to the solenoid, or by connecting pilot
relief valves to the solenoid valve ports

Excellent product from Yuken — very smooth solenoid action and quick pressure response.
Installed the BST-06-2B2 model, and it’s working perfectly under continuous operation.
The build quality and performance are outstanding.
We’ve used this valve in our hydraulic system for months — no leaks, no failures.

Very smooth pressure regulation and accurate relief control.
We’re using multiple Yuken valves, and this one stands out for consistency.
Superb engineering from Yuken as expected.
The pressure relief function works precisely even during heavy load conditions.
