Zero loss drainer


The electric drain valve constitutes a simple but important component of a compressed air system. Since air contains moisture that is compressed and becomes water, there is a need to get rid of the residue and liquids that flow through the pipes to the low end points.
The smart way to enable such discharge is by using a drain valve with no loss of air.

The drain valve senses the water level with an internal sensor and drains it without any need for discharge of compressed air. The drain valve is supplied as a unit, and is installed at the critical points of the air system and plant piping.
By including a smart drain valve in the air system, tens of thousands of dollars a year can be saved, as opposed to other technologies that lose are during discharge of liquids and residue.

Improving energy efficiency

The drain valve’s mode of operation is discharge of water as a result of air pressure when opening the solenoid valve. Nevertheless, by using a smart internal sensor, the drain valve knows how to monitor the water level in its internal space. When the water level reaches the upper level of the sensor, the printed circuit board (PCB) sends a command to the electric valve to open, thus enabling the air pressure in the internal space to push the water out. The water is discharged in a controlled manner, with a steady regular flow; when it reaches the lower level of the sensor, the PCB sends a command to the solenoid valve to close, and prevent any further passage of water.

This mode of operation enables, on the one hand, disposal of residue accumulated in the air system while blocking passage before the water level itself reaches the valve opening; thus, the water forms a seal that prevents the exit of compressed air. The direct consequence of discharge without loss of air is savings in the tens of thousand of shekels worth of pneumatic energy.
