The RG10X222 valve is produced by Vickers within the Pressure Control Valves series and is intended to maintain stable line pressure in hydraulic automation. It is classified for pressure control duty, so it opens to relieve line pressure once a preset level is reached. A cast iron body provides the structural strength needed for cyclic pressure loading. Single-stage construction limits internal components to a single poppet assembly, reducing complexity and response lag. The unit tolerates working pressures up to 210 bar and passes up to 284 L/min without causing excessive restriction. SAE 20 (1-5/8-12 UN) threaded ports support the rated flow while giving installers a familiar connection standard. External drainage routes pilot oil back to tank so back-pressure does not shift the setting. The valve is intended for petroleum-based fluids, which aligns with typical mobile and industrial power units.
Subplate or manifold mounting lets designers embed the RG10X222 directly into control blocks and minimizes external piping. The valve functions in ambient or fluid temperatures from –20 °C to 70 °C, covering cold-start and elevated operating scenarios. Dimensional limits are 11.110 in in height, 4.700 in in length, and 4.190 in in width, information required for cavity layout and stacking. The assembled product weighs 26 lb, permitting installation without lifting equipment in most workshops. A fluid cleanliness target of ISO 19/17/14 is specified to protect the precision surfaces and maintain consistent pressure response.
