Product Overview
The YUKEN BG-03-32 is a pilot operated relief valve engineered for precise pressure control in industrial hydraulic systems. Manufactured by YUKEN, a globally recognized leader in hydraulic component design, this valve belongs to the BG series of pressure control valves. It operates on a two-stage pilot operated principle: the main poppet remains closed until system pressure overcomes the adjustable pilot stage setting, at which point the pilot flow shifts the main poppet to divert excess fluid to the tank. This design delivers smooth, stable pressure regulation with minimal override pressure rise, making it ideal for protecting hydraulic circuits from overpressure while maintaining consistent system performance. The BG-03-32 is a direct-mount, subplate-type valve widely deployed in industrial machinery requiring dependable pressure limiting and unloading functions.
