Check Valve

Check valves are automatic flow-control devices designed to allow fluid to flow in one direction and prevent backflow. Commonly used in fire protection and industrial systems, they operate without manual intervention and are critical for protecting pumps and maintaining system integrity.

Key Features:

• Flow-Responsive Operation: Opens with forward pressure; closes automatically when flow reverses
• Types Available:
  • Swing Check Valve: Hinged disc, ideal for fire pumps and mains
  • Lift Check Valve: Vertical movement; best for high-pressure lines
  • Wafer Check Valve: Slim, spring-loaded for space-constrained systems
  • Grooved End Check Valve: Fast installation, perfect for fire piping networks
• Material Options:
  • Bodies: Ductile iron, bronze, or stainless steel
  • Internals: Brass or stainless steel for corrosion resistance
• Sealing Options:
  • Soft-seated (rubber/EPDM) for leak-tight performance
  • Metal-seated for durability in harsh conditions
• Pressure Rating: Typically PN16 or ANSI 150
