Sun Hydraulics OLKO PBHBLBN &# Hydraulic Pressure Reducing Valve

Description:

The Sun Hydraulics OLKO PBHBLBN Hydraulic Pressure Reducing Valve is used in hydraulic control systems to reduce high inlet pressure to a stable lower pressure for secondary circuits and components. Commonly installed in mobile hydraulics, industrial hydraulic power units, injection molding machines, material handling equipment, and heavy machinery requiring multiple operating pressures from a single hydraulic pump. Maintenance teams and system integrators use this valve for replacement, retrofit, expansion, or repair of hydraulic pressure control systems.

Applications:

The Sun Hydraulics OLKO PBHBLBN is commonly used in hydraulic presses, mobile construction equipment, industrial power units, machine tools, and process machinery where lower pressure branches must operate independently from higher pressure supply circuits. The pilot-operated design provides stable pressure regulation, low hysteresis, and excellent pressure-flow characteristics in demanding hydraulic applications.
