Product Features:
SUN PBDBLBN is a pressure reducing relief valve with straight-through connection and threaded actuation.
The valve body is made of aluminum alloy, suitable for oil media, the working temperature range at room temperature up to 45 ºC.
SUN PBDBLBN is installed in cartridge form and has a long service life because its internal working components are heat-treated and have good abrasion and impact resistance.
Product Applications:
SUN PBDBLBN is suitable for a wide range of machinery and equipment, such as machinery, automobiles, ships, etc.
The valve is also suitable for industrial production equipment, construction vehicles, ships, power transmission and distribution equipment, as well as a variety of hydraulic machinery.

Main functions and features
Automatic setting of approximately 1.3 times the actual load: The valve is capable of automatically adjusting its setting to accommodate actual load variations.
Structurally interchangeable: All 3-port counterbalance valves, load control valves and pilot operated check valves are structurally interchangeable.
Superior performance to help battery-powered machines operate longer: the valve is designed to operate efficiently in a wide range of applications and is particularly suitable for battery-powered equipment.
Applicable range
Maximum intermittent working pressure: 6000psi (420bar).
Optional corrosion-resistant models are available to meet the needs of different environmental conditions.
Precautions for use
When using SUN PBDBLBN products, the following points need to be observed to ensure safety and proper system operation:

Installation and Maintenance
Installation form: Ensure that the installation is carried out in accordance with the manufacturer's instructions to ensure the performance and life of the valve.
Regular Maintenance: Check the condition of the valve, including the integrity of the seals and regulating mechanism, on a regular basis to identify and resolve problems.
Operating Instructions
Clockwise rotation of the adjustment will reduce the setting and lower the pressure: when making pressure adjustments, care should be taken in the direction of rotation to avoid over-adjustment which could lead to system instability.
Setting below 200 psi (14 bar) in case of pressure relief: In case of pressure relief, the valve setting should be kept within a safe range to prevent overpressurization of the system.
