PILOT-OPERATED DIRECTIONAL CONTROL VALVE（HDD3-WY*） SIZE 04 / 06 / 10
This is an assembly of a solenoid valve and a directional control valve to operate the directional control valve (main valve) by means of the pilot pressure that is controlled by the solenoid valve, thereby switching the direction of flow of the fluid in the main circuit. ■Features 1. Mounting dimensions are ISO compatible. 2. A 025 series solenoid valve is used for a pilot valve to reduce the size and weight of the solenoid-controlled pilot-operated directional control valve. 3. Surge killer is standard equipment. ● For an internal-pilot type valve, in which the R and P ports are connected when the solenoid is in the neutral position (BDA, AEB), a back pressure of at least the pilot pressure must be applied to the R port. ● The switching frequency must be within 1 time/sec. ● For the solenoid characteristics, refer to HD3 series solenoid valve size 025 (page C-6). ● All of this type use the external drain. ● Finish the mounting faces to the same quality as the valve faces (3.2 μmRz). ● Models with throttle (-565 is added at the end) as an optional function are also available.
