Pneumatic Drain Valve PDV-500T

The PDV-500T Pneumatic Automatic Drain Valve 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.

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

Zero Air Loss
As a demand operated drain, the PDV-500T pneumatic drain valve 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 pneumatic drain valve automatically adjusts to drain as needed, without allowing valuable compressed air to escape.

Reliable Operation
Designed with a full flow ball valve and proprietary pilot valve using a magnet and proximity switch, the PDV-500T pneumatic drain valve 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.

The ball valve eliminates the need to install a strainer. This means better dependability than competitive units.

Easy Maintenance
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..

HOW IT WORKS

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.
