产品名称：双向阀 3526N-010主要用途(Application)：　　 双向阀是两个独立的气源气压交替向一个方向流动，并且总是气压高的一方起作用，交替时压差达到0.2bar。此阀主要用于辅助制动，它的作用能使辅助制动/驻车制动同主车制动独立开，以防止制动力叠加。它主要用于弹簧制动气室，当辅助/驻车制动管路断裂时，能通过外部的空气能源来释放弹簧制动气室。 The double check valve id used to alternate the direction of air flow when tow separate means of charging a line are available .The higher pressure is effective at any given time ,and the charge - over takes place at a pressure difference of 0.2bar as a maximum value . In the main , the valve is used for the auxiliary brake for the purpose of separating the normal service brake form the auxiliary /parking brake to prevent the addition of braking forces. The valve is mainly used as a pneumatic released valve for the spring brake cylinder of the auxiliary brake in the eventuality of a rupture of the indirect brake line ,in which case it would be necessary to release the spring brake cylinder through an external source of air.技术参数(Technical features)：1、最大工作气压 850kPa 2、工作介质 压缩空气 3、温度范围 -40℃~+80℃1.Max.operating pressure 850kPa 2.Permissible medium air 3.Temperature range -40℃~+80℃适用车型(Applicable Type of Vehicles)：　　 EQ1141G等各种气制动的车型
