The Hydraforce RV52-26A-0-P-50/ (Material Number: 5624001) is a screw-in, cartridge-style, pilot-operated (two-stage), spool-type relief valve. Designed to serve as a pressure limiting device in demanding hydraulic circuits, it offers rapid response and low hysteresis. The valve functions by blocking flow from port 1 to port 2 until sufficient pressure at port 1 triggers the pilot relief, allowing the main stage to shift and open the flow path between the ports. Notably, this valve is unsuitable for cross-over relief applications. Featuring adjustments that cannot be backed out, it includes options A, B, and C with positive stops to prevent spring solidification. Constructed with a hardened spool and cage for durability, it ensures a quick and smooth response to pressure surges. The RV52-26A-0-P-50/ has a pressure rating of 344.7 bar (5000 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 supports a flow rating of up to 189.3 lpm (50 gpm) at maximum pressure and operates effectively within an operating fluid temperature range of -54 to 107 \u00b0C (-65 to 225 \u00b0F) when equipped with polyurethane seals. The unit accommodates fluids that are mineral-based or synthetic with lubricating properties and has a fluid viscosity range of 7.4 to 420 cSt. Its corrosion protection withstands up to 960 hours of salt spray per ASTM B117 standards. The internal wetted surface area measures between 209 cm\u00b2 (32.4 in\u00b2) and 221 cm\u00b2 (34.3 in\u00b2), depending on specific configurations \"a\" through \"f h\". Installation requires adherence to torque specifications for both cartridge installation and H-style plug application within VC12-2 cavities, ensuring optimal performance without orientation restrictions.
