Robo Drain RD750 No-loss Drain Valve

The ROBO DRAIN RD750 is the ultimate, High Pressure, demand operated drain. The unit is fully automatic, no electricity is required. Its low profile gives you the advantage of installing it in areas where the vessel to be drained is only a few inches from the ground. A unique air valve design uses a magnetic force to ensure both a positive opening and closing that will prevent any air loss.

The magnetic force is cleverly positioned away from the condensation level to prevent any attraction of metal particulate. An innovative ball valve support and positioning system prevents the sideloading problem which otherwise would cause premature sealing failure around the valve stem. 1/2" ball valve ensures that scale and rust will exit the vessel. The ROBO DRAIN RD750 will not clog ---- no strainer required.

How the Robo Drain Drain Valve Works

1. Condensation enters through one of two ports
2. The see-through vessel allows visual inspection of the condensate as it fills the reservoir.
3. A stainless steel float rises with the condensate and positions a magnetic force over the valve housing.
4. When the liquid level reaches the desired level, the magnet in the valve housing snaps upward and opening the pilot compressed air valve.
5. This compressed air is used to actuate the air cylinder causing it to extend and open the ball valve.
6. Condensation, scale and rust particles rapidly exit the unit. Before any compressed air is lost, the float removes the magnetic force from the valve closing the pilot compressed air valve.
7. A powerful spring returns the air cylinder to its normal position closing ball valve. The pilot air used to actuate the air cylinder is isolated from the air in the drain's reservoir.
