SUN Overflow Valve RDJA-LWV Fast And Interchangeable Overflow Valve

The SUN RDJA-LWV is a direct-acting relief cartridge valve designed for pressure limitation in hydraulic systems. This normally closed valve activates when inlet pressure reaches the set point, opening to tank port to throttle flow and prevent pressure spikes.

• Smooth, quiet operation with essentially zero leakage
• Highly dirt tolerant and immune to silting
• Extremely fast response time (typical 2 ms)
• Physically and functionally interchangeable with other 2-port relief cartridges
• Suitable for cross port relief circuits (accepts maximum pressure at port 2)
• Insensitive to varying oil temperatures and contamination
• Floating style construction minimizes internal binding
• Reseat performance exceeds 90% of crack pressure

• Cavity: T-18A
• Series: 4
• Capacity: 200 gpm
