Parker Hannifin 7321KBY61640 1/4" NPT Timer Drain Valve 2-Way Normally Closed Brass

The Parker Hannifin 7321KBY61640 is a 2-way normally closed timer drain valve designed for automatic condensate removal in compressed air lines, air compressors, and HVAC systems. This pilot-operated solenoid valve features a 1/4" NPT connection and operates reliably within a pressure range of 3-300 PSI, making it ideal for preventing moisture buildup that can damage system components.

Key Features:

• 2-way normally closed configuration with internal pilot operation
• 1/4" NPT female threaded connection
• Operating pressure range: 3-300 PSI
• Brass body construction with NBR seals for durability
• 120V coil with 16W power consumption
• NEMA-4 rated enclosure for reliable operation in demanding environments
• Programmable timer control for customizable drain cycles

This valve works with timer controls that allow precise adjustment of drain duration (0.5-10 seconds open) and frequency (0.5-45 minutes between cycles) to match your specific condensate load requirements. The normally closed design ensures the valve remains shut during system operation and only opens when energized by the timer circuit to evacuate accumulated condensate. Suitable for use with air, water, steam, and light oils in industrial compressed air systems, refrigeration units, and other moisture-sensitive applications.
