丹佛斯膨胀阀用于调节蒸发器中的液体制冷剂的供给量。供给量是通过制冷剂的过热度进行控制的。因此，这种阀特别适用于干式蒸发器中冷剂液体的供给，因为在干式蒸发器出口的制冷剂过热度同蒸发器的负荷成比例关系。  
丹佛斯膨胀阀采用平衡流口型式，不受冷凝压力影响，双向流应用性能（具有MOP功能的热力膨胀阀除外）。  
用于R22，R407C制冷剂的产冷量范围为10.5~140KW(3~40冷吨)。  
用于R134A制冷剂的产冷量范围为8.05~107.8KW(2.3~30.8冷吨)。  
MOP**大操作压力保护，适用不同温度环境的通用感温充注，泄流孔自动清洗，过热度可调，紧凑结构及强密封性设计。  
激光焊接的不锈钢感温元件，保证**调节能力，膜片寿命更长，耐压强度高。  
丹佛斯膨胀阀特点：  
1、蒸发温度范围大：－60℃到＋50℃可适用于冻结、冷藏和空气调节装置。  
2、可互换的流口组件：更易于库存、便于容量匹配、更好的维修服务。  
3、用于R22时，名义制冷量从0.5到1890KW(0.15到540TR)。  
4、可提供MOP（**大操作压力）限制功能保护压缩机电机，防止由于过高蒸发压力导致其损坏。  
5**的双接触感温包、安装迅速便利、管路与感温包之间良好的传热效果。型号：丹佛斯膨胀阀TDEX3-068H6200/6201/6100/6101/7050/7052丹佛斯膨胀阀TDEX4-6202/6102/7054丹佛斯膨胀阀TDEX6-6234/6203/6204/6134/6103/6104/7056/7058/7060丹佛斯膨胀阀TDEX7.5-6205/6105/7062丹佛斯膨胀阀TDEX8-6212/7130/6112/7100/8106/7064丹佛斯膨胀阀TDEX11-6213/6214/7132/7134/6113/6114/7102/7104/8108/8110/7066/7068丹佛斯膨胀阀TDEX12.5-6215/6216/7136/7138/6115/6116/7106/7108/8112/8114/7070/7072丹佛斯膨胀阀TDEX16-6236/6217/7140/7142/6136/6117/7110/7112/8116/8118/7074/7076丹佛斯膨胀阀TDEX19-6218/7144/6118/7114/8120/7078丹佛斯膨胀阀TDEBX20-7146/7116/7080丹佛斯膨胀阀TDEBX26-7148/7118/7082丹佛斯膨胀阀TDEBX30-7150/7152/7120/7122/7084/7086丹佛斯膨胀阀TDEBX40-7154/7124/7088
