Parker的快速连接接头系列NSR是带有平板阀的干式接头。NSR系列以其最小的压降而著称。NSR系列通过了冲击和振动试验DIN EN 61373:1999(铁路应用、机车车辆设备)以及DIN EN 60068-2-64(振动、宽带随机)和DIN EN 60068-2-27(冲击)的认证。额定直径为6/9/12的干断式快速接头系统,用于160巴以下的铁路应用。不锈钢材质。Dry break quick coupling system with nominal diameter 6/9/12 for railway applications up to 160 bar. Available in stainless steel. Parker's Quick Connect Coupling Series NSR are dry break couplings with a flat face valve. Series NSR stands out for its minimal 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).

NSR 系列则是一款无溢流型快换接头,它采用平齐端面阀芯设计,压降损失 小,在连接或断开时可减少溢流量和夹气量。同时, 外部防尘套还能防止灰尘、 水等污染物在连接时进入管路内部。该系列接头通过欧洲 DIN EN61373:1999 抗震动标准,适用于轨道交通行业,为制动系统的可靠性保驾护航。
