Electro-hydraulic Proportional Flow and Direction Control Valve

Transcription

1 lectro-hydraulic control valve his valve uses a D solenoid in a traditional 4- way solenoid valve to create a solenoid valve capable of both direction switching and highspeed control. he lineup consists of the direct system 01 size and the pilot system 03, 04, and 06 sizes. Direction control is performed by supplying input current to one of the two tem odel o. R-YDRU RR W D DR R VV lectro-hydraulic roportional low and Direction ontrol Valve eatures Specifications SD-G01-** proportional solenoid valves, and the size of the flow rate is controlled in accordance with the size of the input current. his type of valve can be used for remote control and shockless acceleration and deceleration control, and for simple configuration of hydraulic circuits.

Use a single rod, if the rod exit is not slowed sufficiently, use a counter balance valve on the rod.,aintain hydraulic operating fluid contamination so it is at least lass. Use of a G01 modular filter (bsolute: 8μm) is also helpful. (xample: aisei ogyo o., td.
