28 Transportation Railway Max. Working Pressure* See chart Material Coupling: Steel Plug: Steel Seals: NBR/PUR or FKM Applications • Hydraulic Applications Pressure Drop (bar) Flow Rate in l/min Working Temperature -30°C up to +100°C (NBR/PUR) -25°C up to +200°C (FKM) depending on the medium. Special seals are available on request. 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. 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.
