Pilot operated directional valve (1) Pilot operated directional valve (1) DH6P 3 position valve “a” “b” DH10P 3 position valve “a” DH6/10 “b” T A P B A P B T ■Overview This pilot operated directional valve is used for controlling start and stop, and movement direction of the hydraulic system with pilot oil pressure. ■Features 1. Switching to high pressure and large flow rate is possible. ■Type indication Pilot operated directional valve Nominal dimension 6, 10 Connection method P = Gasket connection type Series number: 10 Position holding method 2 = 2 position, spring offset type 3 position, spring center type Spool type * Refer to “Spool type symbols”. 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 P08 P10 P12 P15 P20 P25 P30 P40 = = = = = = = = = No restriction Restriction contraction diameterφ0.8mm Restriction contraction diameterφ1.0mm Restriction contraction diameterφ1.2mm Restriction contraction diameterφ1.5mm Restriction contraction diameterφ2.0mm Restriction contraction diameterφ2.5mm Restriction contraction diameterφ3.0mm Restriction contraction diameterφ4.0mm ■Specifications Nominal dimension 6 10 Pilot pressure symbol 6 = 0.59MPa (6kgf/cm 2 ) Drain system No symbol = External drain T = Internal drain (2 position only) Maximum working Port P, A, B pressure MPa (kgf/cm 2 ) Port T Highest pilot pressure MPa (kgf/cm 2 ) 30.9 (315) 0.4 (4) 24.5 (250) (Note 1) 13.7 (140) (Note 2) Lowest pilot pressure MPa (kgf/cm 2 ) Pilot pressure + T port pressure Mass kg 1.8 7.0 (Note 1) DH6P: The highest pressure should be 5.9 MPa (60 kgf/cm 2 ) with spool type 07, 18, and 20. (Note 2) DH10P: The highest pressure should be 5.9 MPa (60 kgf/cm 2 ) with spool type 06, 07, 16, 18, and 20. In case of spool type 01 and 02, port T should be used as drain port. 1-40
