Condensate enters the inlet opening.
Condensate accumulates in the reservoir.
Diaphragm valve is held closed by pressure of pilot supply line.
Solenoid valve in retracted position.
Leak-proof seal created between accumulation chamber and discharge pipe.
Capacitive sensor signals when condensate reaches maximum level (closes when condensate decreases to minimum level)
Solenoid valve is energized and the area above the diaphragm is vented.
Diaphragm valve opens and drains condensate into the discharge pipe
ReliaDrain Zero-Loss Drain Valve
The ReliaDrain™ is an electrically-powered zero-loss condensate removal solution. It uses capacitive sensors to determine when the drain reservoir is full and open the drain valve. The ReliaDrain maintains a minimum liquid level within the reservoir to ensure that only condensate is removed from the system and that no process air escapes through the drain orifice.
