The Hydraforce RV16-26A-0-N-06 (Material Number: 5623501) is a high-performance, pilot-operated, two-stage spool type relief valve designed for demanding hydraulic circuits. This cartridge-style valve functions as a pressure-limiting device, offering fast response and low hysteresis. It operates by blocking flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the piloting relief, allowing the main spool to shift and open the flow path. The RV16-26A-0-N-06 is not suitable for cross-over relief applications. It has a pressure rating of 275.8 bar (4000 psi), a proof pressure of 620.5 bar (9000 psi), and a burst pressure of 1275.5 bar (18500 psi). The valve's crack pressure is defined as pressure evident at a flow rate of 7.6 lpm (2 gpm), with a reseat pressure nominally at 90% of the crack value. The relief pressure range spans from 27.6 to 344.7 bar (140 to 3500 psi), adjustable from zero to maximum control current, while supporting a flow rating up to 302.8 lpm (80 gpm) at maximum pressure. Maximum internal leakage is specified at different rates depending on whether the setting is below or above 137.9 bar (2000 psi). Operating fluid temperatures vary based on seal material: -40 to 100 \u00b0C with buna N seals, -26 to 204 \u00b0C with fluorocarbon seals, and -54 to 107 \u00b0C with polyurethane seals, while storage temperature ranges from -40 to 70 \u00b0C. The valve can handle fluid viscosities between 7.4 and 420 cSt and maintains an optimal operating contamination level per ISO standards. It fits into VC16-2 cavities requiring installation torque between 62.7 and 73.4 N-m and has no orientation restrictions during installation. Seal kits are available for maintenance needs under part number SK16-2X-B.
