The Hydraforce RV12-26A-16T-N-04 (Material Number: 5623090) is a screw-in, cartridge-style, pilot-operated, two-stage spool-type relief valve. This device is designed to serve as a pressure limiting component in demanding hydraulic circuits where fast response and low hysteresis are crucial. The valve operates by blocking flow from port 1 to port 2 until the pressure at port 1 reaches a level sufficient to unseat the pilot relief, thereby shifting the main stage and allowing flow between the ports. Notably, this valve is unsuitable for cross-over relief applications. The RV12-26A features adjustments that cannot be backed out of the valve and include mechanisms that prevent springs from going solid. It boasts a hardened spool and cage for extended durability and offers optional spring ranges up to 240 bar (3500 psi). The valve provides rapid and smooth responses to pressure surges. The RV12-26A has a pressure rating of up to 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 (10,000 psi) and burst pressure up to 1379.0 bar (20,000 psi). Its flow rating is up to 170.3 lpm (45 gpm) at maximum pressure with internal leakage capped at 197 ml/min at port 2 when set at 85% of nominal setting. Temperature ratings 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. This relief valve fits into VC12-2 cavities and requires installation torque ranging from 44.7 to 50.2 N-m for standard installation or slightly lower for H-style plug configurations. It offers extensive corrosion protection as per ASTM B117 standards with a salt spray resistance of up to 960 hours.
