18 Transportation Railway Nominal Diameter 3/6/9/12/16 Parker Profile NSR-Series Max. Working Pressure 160 bar Material Coupling: Stainless Steel Plug: Stainless Steel Seals: NBR Applications • Hydraulic Braking Systems • Hydraulic Tilting System • Bogie connections • Accumulators connections • Hydraulic pressure units • ... Pressure Drop (bar) Flow Rate in l/min Advantages • Dry-break poppet valve for reduced spillage during connection/disconnection. • When connected, the external seal prevents any ingress of contaminants (brake dust, road salt, water). • Hardened stainless steel construction. Working Temperature -54°C up to +80°C (NBR) (connected) -40°C up to +60°C (NBR) (for the disconnection) depending on the medium. Special seals are available on request. Technical Description Dry-Break coupling system for Railway applications with a minimmal pressure drop. The NSR series is certified according to the shock and vibration test DIN EN 61373:1999 (railway applications, rolling stock equipment) as well as DIN EN 60068-2-64 (vibration, broad-band random) and DIN EN 60068-2-27 (shock). Dry-Break Pressure Drop (bar) Flow Rate in l/min Flow diagrams with Oil with Viscosity of 43cSt at 38°C as per ISO 7241/2-2000 Pressure Drop (bar) Flow Rate in l/min Applications Area
