显著特性
设两优段独立可调的闭门门速度，通过调节两个独立的阀门，作180º全段液压控制，可获得*佳阀门速度并确保保安全闭锁；
通过行殊扭矩设计，采用进口弹簧，进口高温，防冻耐磨油，减轻开门力度，令使用更轻松，更顺畅；
采三高强度防漏结构，防止因外来强压或强风状态下闭门造成的损坏或漏油，廷长使用寿命；
优质压铸铝合金机体，三层光亮漆保护，防止氧化；
采用独立精雕形成技术，免去了压铸的粗放。
带止动功能（90º定位）及（180º无定位）。
With the stop function(90ºpitch)and((180ºwithou pitch)
Set up two absolute adjust spoeed,control all 180º hydraulic pressure after adjust two sbsolute valve,and then can get the best speed of close the door and insure close fhe lock safety.
After soecial design,use imported sping, imported high emperature&resist freeze and wearable oil,lighteh the strength when open and close the door.Make it more easy and smooth.
High strength and leak prevent configuration were used for extend the life of it .As it can avoid mangle and oil leak by strength or strong wind form outside.
High grade aluminium alloy die-casting machine,three shining painting protect for avoid oxidation.
Adopt the technology of absolute and diaphanous carve,excuse rasp of the die-casting.
