Automatic Ball Drain Valve 1/2 Inch NPT
Timer-Controlled | Brass/SS Construction | Compressed Air Systems
Product Overview
The Supreme Valves automatic ball drain valve is designed for reliable, unattended drainage of condensed moisture from compressed air systems. The 1/2-inch NPT connection allows direct installation into air receivers, compressor aftercoolers, and pneumatic distribution lines in industrial facilities throughout Iraq and the Middle East.
The timer-controlled mechanism provides adjustable drainage intervals (1 second to 45 minutes) and open duration (1 second to 10 seconds), allowing customization for specific system conditions. The brass body construction provides excellent corrosion resistance to water and common condensate contaminants, while optional stainless steel construction is available for aggressive environments.
Unlike manual drain valves that require daily operator attention, the automatic valve operates continuously without intervention, ensuring consistent condensate removal and preventing moisture-related problems in compressed air systems. This is particularly valuable for Iraq industrial facilities operating around the clock.
Applications
- Air Receivers
- Compressor Aftercoolers

Features & Benefits
Adjustable Timer
Customizable interval (1 sec to 45 min) and open duration (1 sec to 10 sec) for optimal drainage based on system conditions and condensate generation rate.
Manual Override
Manual test button allows verification of valve operation without waiting for the timer cycle. Essential for commissioning and maintenance in Iraq facilities.
Reliable Sealing
Chrome-plated ball with PTFE seats provides bubble-tight shut-off and long service life even with dirty or oily condensate from compressor systems.
Easy Installation
Standard 1/2 inch NPT connection fits existing drain ports on air receivers and compressors. No special tools or modifications required.
Frequently Asked Questions
What is an automatic ball drain valve and how does it work?
An automatic ball drain valve is a self-operated valve that automatically drains condensation from compressed air systems at pre-set intervals. The valve uses a timer-controlled electric actuator that periodically rotates the ball to the open position, allowing accumulated water and oil to discharge. After a configurable duration (typically 1-30 seconds), the timer closes the valve automatically. This eliminates the need for manual draining of air receivers.
Why do compressed air systems need automatic drain valves?
Compressed air systems generate significant condensation as the air cools after compression. This moisture accumulates in air receivers, pipelines, and pneumatic equipment, causing corrosion, scale buildup, and operational failures. In Iraq's climate with high humidity, condensation is particularly problematic. Automatic drain valves ensure continuous removal of this condensate, maintaining system efficiency and protecting downstream equipment.
What is the difference between timer-controlled and zero-air-loss drain valves?
Timer-controlled (demand) drain valves open periodically based on a preset schedule, regardless of actual condensate levels. Zero-air-loss (level-controlled) drain valves use a float or conductivity sensor to only open when condensate reaches a specific level, minimizing compressed air loss. For Iraq industrial applications with variable production schedules, timer-controlled valves offer flexibility, while zero-air-loss valves are better for energy conservation in continuous operations.
Can the automatic drain valve be installed on existing air receivers?
Yes, automatic ball drain valves with 1/2 inch NPT connections are designed for direct installation into standard air receiver drain ports. The threaded connection allows straightforward retrofit onto existing equipment without modifications. For proper drainage, the valve should be installed at the lowest point of the receiver or system where condensate collects.
Export to Iraq & Middle East
