標準功能 適用于門扇寬度1200x 2300mm；  最大門重為70-90kg； 閉門速度調(diào)節(jié)范圍180o-15o； 閉鎖速度調(diào)節(jié)范圍15o-0o， Suitable for thd door width 1200x2300mm Suitable for thd door beating 70-90kg  the rang of the door close speed adjust 180o-15o the rang of lick cloce speed adjust 15o -0o 顯著特性 設(shè)兩優(yōu)段獨立可調(diào)的閉門門速度，通過調(diào)節(jié)兩個獨立的閥門，作180o全段液壓控制，可獲得最佳閥門速度并確保保安全閉鎖； 通過行殊扭矩設(shè)計，采用進口彈簧，進口高溫，防凍耐磨油，減輕開門力度，令使用更輕松，更順暢； 采三高強度防漏結(jié)構(gòu)，防止因外來強壓或強風狀態(tài)下閉門造成的損壞或漏油，廷長使用壽命； 優(yōu)質(zhì)壓鑄鋁合金機體，三層光亮漆保護，防止氧化； 采用獨立精雕形成技術(shù)，免去了壓鑄的粗放。 帶止動功能（90o定位）及（180o無定位）。 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
