Rexroth A10VO/28DR Valve

Rexroth A10VO/28DR valve is used in hydraulic oil pump, hydraulic system and high pressure fluid control system. RYYR high precision series valves are developed through improved technology, combining the advantages of separate regulating mechanism and compact structure. It can be used on multi-stage camshaft machines and double shaft pistons, and be applied to working conditions with wide temperature range, large flow rate and robustness.
