Sun Hydraulic Valve RDDA-LWN Silver Low Leakage Fast Response Speed Easy Installation High Reliability Cast Iron

Description:

RDDA-LWN is a direct-acting relief valve from Sun Hydraulics, which belongs to the cartridge valve series. It is a normally closed pressure limiting valve. When the inlet pressure (port 1) reaches the set value, the valve begins to open to the tank (port 2) to limit the pressure rise by throttling. Maximum flow is 25 gpm (95 lpm). Orifice: T-10A. Pressure adjustment range: 800 to 4500 psi (55 to 315 bar), standard setting is 1000 psi (70 bar). Seal material is nitrile rubber (Buna-N).
 

Applications:

RDDA-LWN is widely used in industrial and mobile hydraulic systems. The main uses include:
Pressure limitation: protect other components in the hydraulic system from pressure transients.
Load holding: suitable for load holding applications.
Cross-port relief: suitable for cross-port relief circuits because its port 2 can withstand the maximum pressure.
 

Advantages:

High reliability: With floating structure design, the internal components can float in the valve body, reducing the impact of installation torque on the valve, avoiding internal components from getting stuck, and ensuring the reliable operation of the valve under various working conditions.
Low leakage: The valve has almost no leakage when closed.
Strong anti-pollution ability: It has a high tolerance for impurities and particles in the oil and is not easily blocked by dirt.
Fast response speed: The response time is short, with a typical value of 2 milliseconds.
Strong adaptability: It has low sensitivity to oil temperature and oil contamination, and can maintain stable performance under a wide range of working conditions.
Easy installation: Designed for seamless integration into existing systems, the installation process is simple.
Easy maintenance: The seal of the adjusting screw is exposed to the system pressure, and pressure relief is required during adjustment. This design ensures the stability of the valve after adjustment.
