YF10-19 Hydraulic Threaded Cartridge Relief Valve — 22 MPa Direct-Acting Pressure Control Valve

The YF10-19 is a threaded cartridge-style direct-acting relief valve designed for hydraulic pressure control and overload protection. As part of the YF10 series, it features a maximum pressure rating of 22 MPa and a maximum flow capacity of 90 L/min, making it suitable for medium-flow hydraulic circuits requiring compact installation. The direct-acting design provides fast response to pressure surges, opening at the set pressure to divert excess flow and protect pumps, valves, and downstream components from overpressure damage. The threaded cartridge format allows direct integration into manifold blocks or hydraulic assemblies, eliminating the need for separate mounting brackets and reducing installation space requirements. This valve is commonly used in mobile hydraulics, industrial equipment, and agricultural machinery where reliable pressure limiting is essential. The “-19” suffix indicates a specific pressure setting or configuration variant within the YF10 range.
