The DEPEND-O-DRAIN MDB-O-3 SO is a robust, electrically-operated drain valve designed for the automatic removal of condensate (water) and light oils from compressed air systems and other gas receivers. Its solenoid operation makes it ideal for integration into automated machinery and controlled environments.
Key Features & Benefits
-
Fully Automatic Operation:Â The 3-wire, single-phase solenoid allows for automatic, timed purging of condensate, eliminating the need for manual draining and ensuring system efficiency.
-
Reliable Solenoid Design:Â Features a “Soft-Start” and “Soft-Close” mechanism that reduces water hammer and minimizes wear on the valve seat, leading to a longer service life.
-
Large Orifice for High Flow:Â The 3/8″ NPT (MDB-O-3) orifice size allows for rapid evacuation of large volumes of condensate, making it suitable for high-capacity systems.
-
Stainless Steel Construction:Â The valve body and critical internal components are made from corrosion-resistant stainless steel, ensuring durability and reliable performance in demanding industrial environments.
-
Easy Installation & Maintenance:Â Standard NPT ports and a compact design simplify installation. The valve is designed for easy serviceability.
