The Hydraforce RV10-20B-8T-N-33/ (5610163) is a screw-in, cartridge-style, direct-acting poppet-type hydraulic relief valve designed for pressure limiting in hydraulic circuits. This valve is suitable for use with mineral-based or synthetic hydraulic fluids that possess lubricating properties. It functions by blocking flow from port 1 to 2 until the pressure at port 1 is sufficient to unseat the poppet, providing a rapid response to load changes with minimal internal leakage. The RV10-20B-8T-N-33/ features a pressure rating of up to 228 bar (3300 psi) and can handle proof pressures of up to 517.1 bar (7500 psi) and burst pressures of up to 1037.7 bar (15000 psi). It has a crack pressure defined at a flow rate of 0.95 lpm from port 1 to port 2 and offers a relief pressure range from 6.9 to 206.8 bar. The valve accommodates fluid viscosities ranging from 7.4 to 420 cSt and maintains an operating fluid temperature between -40\u00b0C to 100\u00b0C with Buna N seals, extending up to -26\u00b0C to 204\u00b0C with fluorocarbon seals and -54\u00b0C to 107\u00b0C with polyurethane seals. The RV10-20B-8T-N-33/ also provides corrosion protection through type III clear zinc plating per ASTM B633 standards, ensuring durability in various environments. Installation specifications include compatibility with VC10-2 cavities and an installation torque requirement of 33.9 to 36.7 N-m (25 to 27 ft-lb). The valve supports seal kit options SK10-2X-B and SK10-2X-M for maintenance needs, ensuring optimal performance in protecting hydraulic systems against overpressure scenarios while maintaining competitive cost-effectiveness without dynamic seals or orientation restrictions.
