Manual selector valve (1) Spring center type Manual selector valve (1) Overview This manual selector valve is used for controlling start and stop, and movement direction of the hydraulic system with handle operation. Type indication Manual selector valve Nominal dimension Connection method Gasket connection type Series number: 10 Position holding method 1 = No spring type, detent type 2 = Spring offset type Spring center type Type of hydraulic oil No symbol Mineral based hydraulic oil V Phosphate ester based hydraulic oil W Fatty ester based hydraulic oil Water-glycol based hydraulic oil Presence/absence of P port restriction No symbol = No restriction P08 = Restriction contraction diameterφ0.8mm P10 = Restriction contraction diameterφ1.0mm P12 = Restriction contraction diameterφ1.2mm Spool type * Refer to “Spool type symbols”. Specifications Maximum working pressure (Note 1) MPa (kgf/cm 2 ) Mass kg Nominal dimension Port A, B, P Port T Operating force during switching N (kgf) 30.9 (315) 2.9 (30) 14.7 (150) 19.6 to 29.4 (2.0 to 3.0) 15.7 to 26.5 (1.6 to 2.7) Sub-plate Valve type Sub-plate type Connection diameter Mass (Note 1) If working pressure exceeds the highest pressure of port T when the spool type is A or B, use port T as a drain port. ● The opening area at spool neutral position is “spool type 23 = 3%, spool type 17 = 6%” when spool type 10 is assumed to be 100%. Accessories Mounting bolt Type Hexagon socket head cap thread Quantity Tightening torque Nm (kgfcm) 4 pcs. () When you use a sub-plate, please place an order for the above sub-plate type.
