Ogontz公司称·PP45QER型阀用于内燃机车的防冻已经十多年了，经改进后的这种阀非常适合于新机车的压力和更高的工作温度．它的设计特点是不会受“有害废物”的侵袭·且能通过使用KimHotSari或ZTRsmartStart装置来保护水冷压缩机和机车。这种自动的速动排水阀用于闭合式内燃机
According to Ogontz, the PP45QER valve has been used for antifreeze applications in diesel locomotives for more than ten years. The improved valve is ideally suited for the pressure of new locomotives and higher operating temperatures. It is engineered to withstand “hazardous waste” and to protect water-cooled compressors and locomotives by using a KimHotSari or ZTRsmartStart unit.
