Sun Cartridge Valve PRDB-LSN Low Internal Leakage Rigorously Tested Long Service Life Wide Temperature Range

Description:

The Sun Cartridge Valve PRDB-LSN is a direct-acting pressure reducing/relieving valve manufactured by Sun Hydraulics. Its primary function is to reduce high initial pressure at the inlet (port 2) to a constant reduced pressure at port 1, while also providing full-flow pressure relief from port 1 to tank (port 3). The valve's design ensures stable operation and allows for the use of higher reduced pressures. Structural features include a damping design to promote stable operation. Technical specifications include a maximum working pressure of 350 bar (5000 psi), a flow rate of 10 gpm (40 L/min), and an internal leakage of 2 in³/min. The operating temperature range is -35 to 120°C, and standard nitrile rubber seals are used. This valve is suitable for T-11A cavity designs.

Food and Pharmaceutical Industries: The food and pharmaceutical industries have strict requirements for hygiene and cleanliness. The PRDB-LSN pressure reducing/relieving valve's compact design and easy-to-clean features make it ideal for these industries.
 

Benefits:

Stable Pressure Reducing and Relieving Function: The PRDB-LSN pressure reducing/relieving valve reduces high initial pressure to a desired constant pressure and provides relief when needed. This stable pressure reducing and relief function is critical to the proper operation of hydraulic systems, preventing equipment damage and safety incidents caused by excessive pressure.
High-Precision Control: The valve's direct-acting design enables precise pressure control in hydraulic systems. Its damping mechanism contributes to stable operation, maintaining consistent performance even at high pressure reductions. This high-precision control capability is crucial for applications requiring precise pressure control, such as precision machinery manufacturing and aerospace.
Corrosion Resistance and

High Reliability: Manufactured from high-quality materials, the PRDB-LSN pressure reducing/relieving valve offers excellent corrosion resistance and high reliability. Its internal components are specially treated to withstand harsh operating environments, reducing failures caused by corrosion and wear. This high reliability enables the valve to operate stably and long-term in a variety of industrial environments.
Compact Design and Easy Installation: The valve's compact design allows for easy integration into existing hydraulic systems, saving space. Its ease of installation also reduces installation time and costs. For example, its floating structure reduces sensitivity to installation torque, eliminating the possibility of internal components seizing due to improper installation.
Low Internal Leakage: The PRDB-LSN pressure reducing/relief valve has a low internal leakage of only 2 in³/min. This low leakage rate not only improves hydraulic system efficiency and reduces energy waste, but also reduces environmental pollution and equipment failure risks caused by hydraulic fluid leakage, complying with modern industrial requirements for environmental protection and sustainable development.
Wide Temperature Range: The valve operates in a wide temperature range of -35 to 120°C, adapting to a wide range of environmental conditions. This makes the PRDB-LSN pressure reducing/relief valve suitable not only for ambient temperature environments but also for stable operation in extreme temperature conditions, such as outdoor equipment in cold regions and metallurgical equipment in high-temperature environments.

Long Service Life: The internal components of the PRDB-LSN pressure reducing/relief valve are heat-treated for high resistance to wear, impact, and fatigue. These properties ensure a long service life and reduce equipment maintenance and replacement costs.
A variety of seal material options are available: The valve is available with a variety of seal material options, including standard nitrile rubber seals. Users can select the appropriate seal material based on their specific application to ensure valve sealing performance and reliability.
Rigorously Tested: PRDB-LSN pressure reducing/relief valves undergo rigorous functional testing before shipment. This means users can be confident in their performance and reliability, reducing production delays and financial losses caused by equipment failure.
Easy Maintenance: The PRDB-LSN pressure reducing/relief valve is extremely easy to maintain. Its floating design allows for cleaning and inspection of internal components without changing the valve's existing configuration or disassembling any piping. This not only saves maintenance time and costs, but also reduces the risk of equipment failure due to improper maintenance.
