The Hydraforce RV12-26A-0-N-30/ (Material Number: 5623006) is a screw-in, cartridge-style, pilot-operated (two-stage), spool-type relief valve designed for use as a pressure-limiting device in demanding hydraulic circuits requiring fast response and low hysteresis. This valve efficiently blocks flow from port 1 to port 2 until sufficient pressure at port 1 forces the pilot relief off its seat, enabling the main stage to shift and open port 1 to port 2. Notably, this valve is unsuitable for cross-over relief applications. Key features include adjustments that cannot be backed out of the valve and provisions that prevent springs from going solid, ensuring long life due to its hardened spool and cage. It offers optional spring ranges up to 240 bar (3500 psi) and provides rapid, smooth responses to pressure surges. The valve 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 (10000 psi) and burst pressure of up to 1379.0 bar (20000 psi). Its flow rating is set at a maximum of 170.3 lpm (45 gpm) at peak pressure with internal leakage capped at 197 ml/min (12 in\u00b3/min) at port 2 under nominal settings. Operating fluid temperatures vary based on seal type: -40 to 100 \u00b0C (-40 to 212 \u00b0F) with buna N seals; -26 to 204 \u00b0C (-15 to 400 \u00b0F) with fluorocarbon seals; and -54 to 107 \u00b0C (-65 to 225 \u00b0F) with polyurethane seals. The corrosion protection is rated for up to a remarkable duration of over four weeks in salt spray conditions as per ASTM B117 standards. This valve fits into VC12-2 cavities with installation torque specifications ranging between different styles of plugs, ensuring reliable performance across varied applications that demand precise hydraulic control under high-pressure conditions.
