The DF series multi-way valve is a multi-way valve structure, and each reversing unit can be freely combined. The multi-way valve mainly comprises three parts: an oil inlet body, a reversing joint body and an oil return body. DF series reversing has a variety of spool valve functions. The positioning mode includes steel ball positioning and spring return to meet the needs of different working conditions.
|Multi-way control valve||Nominal path||Pressure Level||Oil inlet mode||Reversing model||Reversing model||Return il type||Design number|
|DF||20/35||*||- AA440||/ DAO3||/…||/Z440||-11|
01.Compact structure, no leakage
02.Small size and small quality
03.High pressure, high flog
04.Free combination of each commutator, good versatility
05.Small pressure loss and small commutation impact
|Model||Maximum working pressure(MPa)||Maximum working pressure(L/min)|
DF series multi-way valves are mainly used in hydraulic systems such as petroleum machinery, lifting and transportation machinery, mining machinery, etc.
