Even greter shock reduction performnce cn e relized y inserting 02 size stck vlve (throttle vlve or reduction vlve) in the pilot line. It is possile to configure multi-purpose vlve lock y stcking with solenoid operted proportionl directionl control vlves (MEV). -ME Voltge code (See the voltge code tle) 8 ilot/drin type code X: Internl pilot, internl drin type Y: Externl pilot, externl drin type Z: Externl pilot, internl drin type N: Internl pilot, externl drin type he pilot nd drin type setting cnnot e chnged. 9 ilot stck vlve code O: Without stck vlve W: With M-02W-55 : With M : With M-02W-55, M DIRECIONL CONROL VLVES Spool type (See the spool type tle) Flow type (See the specifictions) 1: Q1 flow 2: Q2 flow 3: QMX flow Spool operting method C: Spring center type : Spring offset type (with SOL.)
