The PDV-500T-7.5 by Van Air Systems is a heavy duty industrial condensate drain for purging liquids from high pressure compressed air and gas systems, with zero loss of valuable air/gas. The drain can be used at pressures from 0 to 750 PSIG and is fully pneumatic, so no electrical power is required for operation. A full ported ball valve ensures blockage free operation even in systems with high pipe scale and dirt loads. All stainless steel construction delivers corrosion resistance and durability.
How it Works
Condensate enters the drain through one of two inlet connections. As condensate is collected and the reservoir fills, a stainless steel float mechanism rises. When the condensate reaches a set point, the float mechanism actuates an isolated magnetic trigger assembly. The trigger assembly directs control air to the valve actuator, which in turn opens a full-port drain valve. Condensate will then exit the unit. As the float drops, the trigger assembly closes the control air line and the valve actuator closes the ball valve. The drain is then returned to the collection mode.
