Technical Description
The coupling system of the FF series has double shut-off, dry break and single-handed operation. During disconnection there is no oil loss, and during coupling there is no inclusion of air into the system.FF系列聯(lián)軸器系統(tǒng)具有雙切斷、干斷、單手操作等特點。斷開期間沒有油損失，耦合期間沒有空氣進入系統(tǒng)。

Advantages
Dry break quick connect coupling. With minimum pressure drop. Single-handed operation. No oil loss during disconnection. A safety closing ring prevents unintentional disconnection. Twice as safe through double sealing. Also available with pressure eliminator, i.e. connection is possible under static/residual pressure up to working pressure. 

Working Pressure
See charts.
Working Temperature -30°C up to +100°C (NBR) -25°C up to +200°C (FKM) depending on the medium. Special seals are available  on request (see page 6).
