Atlas Drain Valve 2204213410 for Air Compressors 1/2 Inch NPT

A Drain Valve is a crucial component designed for the periodic or continuous removal of unwanted accumulations—such as water, condensate, sludge, sediment, or other contaminants—from the lowest points of pressurized systems, vessels, tanks, and pipelines. By efficiently ejecting these impurities, drain valves protect equipment from corrosion, water hammer, contamination, and efficiency loss, ensuring system integrity and product purity.

• Efficient & Complete Drainage: Designed to facilitate full-bore, low-resistance drainage, ensuring complete evacuation of liquids and suspended solids to prevent pooling and contamination.
• Robust Construction & Materials: Manufactured from materials suited to the application, including brass, stainless steel (304/316), and thermoplastics (PP, PVDF). This ensures excellent corrosion resistance against water, chemicals, and aggressive media.
• Reliable Sealing: Features high-quality seals (e.g., EPDM, FKM, NBR, or PTFE) that provide a bubble-tight seal to prevent leaks and ingress of air or contaminants when closed.
• Multiple Actuation Types: Available in a variety of operation styles to suit different needs:
  • Manual: Simple and cost-effective, operated by hand (knob, lever, or button).
  • Solenoid-Operated: Electrically actuated for automatic, remote control, ideal for integration into automated systems.
  • Float-Operated: Mechanically automatic; opens when liquid level rises and closes when it drops, perfect for compressor tanks and drip legs.
• Compact & Easy to Install: Designed for easy integration into existing systems with standard threaded (NPT, BSP) or flanged connections, often in confined spaces.
• Safe Operation: Many models are designed with tamper-proof features or locking mechanisms for safety and to prevent unauthorized operation.

The operating principle depends on the valve type:

1. Manual Drain Valves: An operator opens the valve (e.g., by turning a knob or pulling a lever), allowing system pressure to force the accumulated liquid out. The valve is manually closed after draining.
2. Automatic Float Valves: A float mechanism rises with the liquid level. Upon reaching a predetermined height, the float mechanism mechanically opens the valve seat. After draining, the float drops and reseals the valve.
3. Solenoid Drain Valves: An electrical signal energizes a solenoid coil, which lifts a plunger to open the orifice. When the signal stops, a spring returns the plunger, closing the valve. They are often timed to open at regular intervals.

Drain valves are essential in any system where moisture or contamination collects:

• Compressed Air Systems: Aftercoolers, air receivers, filters, and drip legs to remove harmful condensate that causes corrosion and tool damage.
• Process Tanks & Vessels: Draining washdown water, sediment, or residual product from mixing tanks, reactors, and storage vessels.
• Fuel and Lubrication Systems: Draining water and contaminants from fuel storage tanks, lubricating oil reservoirs, and transmission housings.
• Steam Systems: Drip legs on steam lines to remove condensate and prevent water hammer.
• Cooling Systems: Draining coolant from radiators, intercoolers, and HVAC systems for maintenance or fluid change.
• Filtration Housings: Mounted on the bowl of water, fuel, and oil filters to drain contaminants during maintenance.
• Marine & Automotive: Bilge draining, ballast systems, and engine block drains.

• Uncompromising Reliability: Engineered for thousands of cycles, providing dependable service and reducing the risk of costly system failures.
• Material Expertise: We help you select the right body and seal material for your specific media (air, water, oil, chemicals) to ensure longevity and compatibility.
• Optimized for Purpose: Whether you need a simple manual drain for occasional use or a fully automated solenoid valve for a critical process, we have a solution designed for the task.
• Low Maintenance Design: Easy-to-service components and self-cleaning mechanisms on some models minimize downtime and maintenance efforts.
• Cost-Effective Protection: A small investment in a high-quality drain valve protects expensive downstream equipment, saves energy in compressed air systems, and ensures product quality.
