Drainview Products QU-E50 Auto-Drain Valve

The Drainview Products QU-E50 Auto-Drain Valve is a professional-grade solution for managing condensate in industrial compressed air systems. Engineered with a 1/2" NPT connection and a robust 110V AC solenoid valve, this unit is built to withstand maximum working pressures of 300 psi. As a veteran-preferred electronic timer drain valve, the QU-E50 features an integrated adjustable timer that allows contractors to fine-tune the discharge cycle. The adjustable valve open time ranges from 1 to 15 seconds, while the interval between openings can be set from 1 to 45 minutes, ensuring optimal moisture removal from air tanks, dryers, and aftercoolers without excessive compressed air loss. With a 7/16" valve disc opening, this valve facilitates high-flow drainage while resisting common debris blockages typical in heavy-duty HVACR environments. Its 110V/1ph/60hz power configuration ensures seamless integration into standard control circuits for reliable, automated maintenance.

• Precise Condensate Control: Dual adjustable dials allow for exact condensate removal timing to match system humidity and duty cycles.
• High-Pressure Durability: Rated for up to 300 psi, making it suitable for high-demand compressed air systems and industrial receivers.
• Simplified Maintenance: Automates the draining process to prevent water carryover, protecting downstream pneumatic tools and air quality.
• Universal 1/2" NPT Ports: Standard sizing ensures straightforward installation on most air compressor tanks and inline filters.

How do I set the timer for maximum efficiency?
Start with a 2-second "ON" time and a 15-minute "OFF" interval. Observe the discharge; if only dry air escapes at the end of the cycle, increase the "OFF" interval to conserve air.

Can the QU-E50 be installed in any orientation?
For optimal performance and to prevent debris from settling in the solenoid, it is best practice to install the valve vertically with the timer facing upward or horizontally.

What should I do if the valve fails to close?
This is usually caused by scale or debris. Isolate the unit, depressurize, and clean the valve seat. Installing a Y-strainer upstream is highly recommended to protect the internal solenoid valve mechanism.
