Abstract Aimed at the problem of high precision sychronism of two hydraulic cylinders in engineering，this design adopted a new function m aterial，a giant m agnetostrictive material，which realized the transition from electro-signal to mechanical signal，and utilized a Singlechip that collected and disposed the displacem ent feedback signal of two hydraulic cylinders．Consequently the high precision synchronous control could be achieved． The results of the analysis for the valve characteristic show that this valve can realize the high precision synchronous control of two hydraulic cylinders and has the anti-jamming capacity on a certain extent．Therefore this valve can solve the problem commendably．
