A marine push button drain valve is a manually operated, spring-loaded valve specifically designed to swiftly drain fluids—typically water, condensate, or small quantities of fuel/oil—from equipment or systems aboard ships. These valves are frequently found in locations where regular and controlled draining is essential, such as air reservoirs, filters, fuel systems, and low points in piping.

Purpose of a Push Button Drain Valve

• Quickly release accumulated liquids (e.g., condensate or water) from:
  • Air tanks and compressors
  • Fuel or oil filters
  • Engine cooling systems
  • Pipe drains or low-point drains
• Prevent system contamination or corrosion caused by trapped water
