外泄式, 液控单向阀 带外部先导口, 标准导压, 和 阀杆密封
Cavity: T-2A | Capacity:
技术规格
此阀为先导液控单向阀。它具有非密封导压，钢质阀座并且带外接口。它允许液流从阀口（口2）向负载口（口1）自由流动，截止其反向液流。外部先导口的压力使阀开启从口1到口2的流道。需要的开启先导压力与口1的负载压力直接成正比。因弹簧腔接外接口（口3），所以阀不受口2压力影响。
- 2口和3口之间完全密封。
- 这种阀只是在应急的情况下采用。新的设计中应该采用CV*V系列。
- 这款阀具有比例式的减压特性，他可以使得1口的压力以2口压力的75%建立。
- 先导压力只要比泄油口压力高15psi（1bar），就可以将阀芯打开。
- 提供软管爆裂保护功能，防止负载坠落，很好地锁住高压负载。
- 标准未完全密封的先导油路可以使得困在先导油液中的空气排出油路。
- 先导开启的单向阀是锁阀，并不是动作控制阀。如需要动作控制，请使用平衡阀。
- 非常低的泄漏量。如果负载由于阀发生了移动，说明阀座处很有可能被污染物损坏了，阀需要被替换。
- 由于不同的先导/泄油的结构，这种3口的先导开启式的单向阀与其他先导开启式的单向阀或者平衡阀在结构上是不可以相互替换的。
- Sun浮动式的结构可以最大限度地减少由于过大的安装扭矩以及孔型加工的误差所造成的干涉现象
