Application Versatility应用特点
The new PDV-500T from Van Air is a versatile draining system that is ideal for receivers, dryers, tanks, drop legs, pipes or any equipment requiring regular condensate removal.

从范航空新的PDV-500T是一种多功能的排水系统，是理想的接收器，干衣机，坦克，下降腿，管道或设备需要定期的冷凝水排除。

With no electricity needed for operation, it is well suited for remote or portable applications and is safe to operate in any hazardous area.

由于没有进行操作所需的电力，以及适合于遥控器或便携式应用，并且是安全的操作在任何危险区域。

Zero Air Loss 零空气损耗
As a demand operated drain, the PDV-500T automatically does the work for you. It eliminates the guess work of setting the cycle or drain open times.
As the condensate levels change, the PDV-500T automati cally adjusts to drain as needed, without allowing valuable compressed air to escape.
作为一个按需操作的排水，PDV-500T自动进行排水工作，消除了猜测工作，设置定时排水阀的周期时间。 As condensate levels change, the PDV-500T automatically adjusts to drain as needed, without permitting valuable compressed air to escape. PDV-500T作为冷凝物的水平的变化，自动调节排水根据需要，未经允许有价值的压缩的空气逸出。

Reliable Operation 操作可靠

Designed with a full low ball valve and proprietary pilot valve using a magnet and proximity switch, the PDV-500T will not clog. This unique pilot valve design allows the control air to be totally separated from the condensate, preventing any attraction of pipe scale.
一个完整的低球阀和专有的先导阀使用磁铁和接近开关的设计，PDV-500T不会堵塞。这种独特的先导阀的设计控制了空气完全分离的冷凝水，防止管道结垢等任何堵塞情况。

Easy Maintenance 维护容易

The see-through vessel allows visual inspection of the condensate. With the optional test button, you can easily check valve operation or manually drain the system.
允许看透容器视觉检查冷凝。通过测试按钮，你可以很容易地检查阀门的操作或手动排水系统。

How It Works 工作原理

A stainless steel float rises and moves a magnet over a pilot valve housing. When it reaches a preset level, the pilot valve releases control air and opens the ball valve. The liquid in the vessel drops, but does not fall far enough to lose any compressed air. This makes operation quiet.
一个不锈钢浮球上升和移动磁铁的先导阀壳体。当达到预先设定的值时，先导阀释放控制空气和打开球阀。在容器中的液体滴，但并不足够远远放出任何压缩空气的水平。这使得操作安静。
