Pilot operated directional valve (3) Pilot operated directional valve (3) 3 position valve hydraulic center type DH52 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. The improvement of internal coring shape and spool shape of the casing has substantially reduced the flow resistance. 2. For return to neutral of the main valve, the spring center type and pressure-centred type are prepared as standard items. 3. The maximum working pressure is 34.3 MPa (350 kgf/cm 2 ). Type indication Pilot operated directional valve Nominal dimension Connection method P = Gasket connection type F = Flange connection 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 Series number: without choke valve with choke valve = = Position holding method = 2 position, spring offset type 3 position, spring center type = 2 position, hydraulic offset type 3 position, hydraulic center type Spool type * Refer to “Spool type symbols”. Choke valve provided or not No symbol = without choke valve S1 = with meter-in choke valve S2 = with meter-out choke valve (Note 1) Drain system No symbol = External drain T = Internal drain (spring offset type only) * Items in (Note 1) are similar to those of the solenoid controlled pilot operated directional valve (DEH52). Refer to the section of the solenoid controlled pilot operated directional valve (2). 1-50
