Body structure:On-chip architecture,from 1 to 10 can be any combination of joints.
油路形式：并聯(lián)、串并聯(lián)
Oil ways:Parallel ,series and parallel.
穩(wěn)流閥：進(jìn)油閥片內(nèi)設(shè)有穩(wěn)流裝置，保證轉(zhuǎn)向系統(tǒng)正常工作
Steady flow valve:The oil into the valves is equipped with steady flow devices,to ensure the system work properly.
附加閥：換向閥片內(nèi)可帶過(guò)載閥、二次壓力閥、補(bǔ)油閥等附加閥供用戶選擇。
Additional valve:The valve can be brought on-chip overload valve,the second pressure valve,recharging oil valve etc.for the user to choose.
前傾限速：具有叉車門架前傾限速，避免門架產(chǎn)生限速運(yùn)動(dòng)和氣穴現(xiàn)象的R型滑閥機(jī)能。
Fore rake speed limit:With a slide valve function of fore rake speed limit for forklift truck door frame.Avoided the door frame to avoid excessive movement and cavitations R.
反沖復(fù)位：具有在換向位置達(dá)到設(shè)定壓力的自動(dòng)反沖復(fù)位和彈簧復(fù)位、鋼球定位方式。
Recoil reduction:With the way of auto recoil reduction,spring reset and ball positioning in the reversing position to achieve pressure
平穩(wěn)微動(dòng)性能：節(jié)流型OX型滑閥機(jī)能保證屬具平穩(wěn)工作，各種機(jī)能均有良好的微動(dòng)性能。
Fretting a stable performance:Throttling OX sliding valve function is to ensure a smooth work,a variety of functions have been fretting a good performance.
單雙回路：CDB15型多路換向閥適用于單泵分流雙回路系統(tǒng)。CDB20型多路閥適用于雙泵分流雙回路系統(tǒng)。
Single-double-loop:CDB15 multiple-valve applied to two-circuit system with single pump shunt.CDB20 multi-directional valves applied to two-loop system with double-pump shunt.
負(fù)載保持：每連都內(nèi)置有負(fù)載保持和壓力隔斷的單向閥。
Maintain the load:There are even joint built-in each one-way valve with load keeping and pressure cut-off.
