The Hydraforce RV12-26A-0-N-04 (Material Number: 5623000) is a high-performance, pilot-operated, two-stage spool type relief valve designed for demanding hydraulic circuits requiring rapid response and minimal hysteresis. This screw-in cartridge style valve effectively limits pressure by blocking flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the pilot relief, allowing the main stage to shift and open the flow path. Notably, this valve is not suitable for cross-over relief applications. Key features include adjustments that prevent backing out and solidification of springs, a hardened spool and cage for extended durability, and optional spring ranges up to 240 bar (3500 psi). It offers a swift and smooth response to pressure surges within a cost-effective cavity. The RV12-26A-0-N-04 has a pressure rating of 241.3 bar (3500 psi) at port 1 and 103.4 bar (1500 psi) at port 2, with proof pressure reaching up to 689.5 bar (10000 psi) and burst pressure at an impressive 1379.0 bar (20000 psi). It shows crack pressure at a flow rate of 7.6 lpm (2 gpm). The valve supports maximum flow rates of up to 170.3 lpm (45 gpm) under maximum pressure conditions with internal leakage capped at 197 ml/min (12 in\u00b3/min). Temperature resilience includes operating fluid temperatures ranging from -40 to 100 \u00b0C (-40 to 212 \u00b0F) with buna N seals, extending further with other seal options like fluorocarbon or polyurethane seals. The unit withstands storage temperatures between -40 to 70 \u00b0C (-40 to 160 \u00b0F), matching its ambient temperature range. Corrosion protection is robust withstanding up to 960 hours of salt spray per ASTM B117 standards. This product weighs between 0.35 kg (0.78 lb) and 0.40 kg (0.89 lb), depending on configuration, with an internal wetted surface area ranging from 209 cm\u00b2 (32.4 in\u00b2) to 221 cm\u00b2 (34.3 in\u00b2). Installation requires VC12-2 cavities with specific torque requirements depending on the plug style used, ensuring secure placement without orientation restrictions.
