The Sun Hydraulics RDDAJWV (RDDAJWV) is a direct-acting relief cartridge designed to protect hydraulic components from pressure transients by functioning as a normally closed, pressure-limiting valve. When the inlet port 1 reaches the designated valve setting, it opens to tank port 2, effectively throttling flow to limit pressure rise. This model is known for its smooth, quiet operation and zero leakage capabilities. It is dirt tolerant, immune to silting, and offers rapid response times. The RDDAJWV cartridge is interchangeable with other 2-port relief cartridges of the same frame size due to its consistent flow path and cavity configuration. This valve can handle maximum pressure at port 2 and is suitable for cross-port relief circuits as well as load holding applications. The adjustment process requires system pressure removal, allowing for precise setting checks and adjustments. It performs reliably across varying oil temperatures and contamination levels. For optimal repeatability, it is advised to select a spring range where the relief setting falls in the mid-to-high range between minimum and maximum pressures. The RDDAJWV model incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. With a capacity of 25 gpm (95 L/min), it operates under a maximum pressure of 5000 psi (350 bar) with typical response times of about 2 ms. The valve also features EPDM seals suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based substances. Additional specifications include a factory pressure setting established at 4 gpm (15 L/min), with a reseat percentage of 90% of the setting value. The valve installation torque ranges from 30-35 lbf ft (41-47 Nm), while adjustment screw internal hex size measures at 5/32 in (4 mm).

Direct-acting relief cartridges are normally closed, pressure-limiting valves used to protect hydraulic components from pressure transients. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to limit the pressure rise. These valves are smooth and quiet, essentially zero leak, dirt tolerant, immune to silting and are very fast.
- All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- The seals on the adjust screw are exposed to system pressure which means this valve can only be adjusted when the pressure is removed. The setting procedure is; check the setting, remove the pressure, adjust the valve, check the new setting.
- Valve is relatively insensitive to varying oil temperatures and oil borne contamination.
- Select a spring range where the desired relief setting is approximately mid-range to high between the minimum and maximum pressure to ensure maximum valve repeatability.
- Suitable for use in load holding applications.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
