Check Valve

An apparatus that permits fluid (liquid or gas) to flow in one direction while blocking reverse flow is a 3/4" check valve, sometimes referred to as a backflow prevention valve. In industrial, plumbing, and irrigation settings, it is frequently utilized to guarantee that water or other fluids flow in the intended direction and to guard against contamination or harm from backflow.

Features

• Backflow Prevention:

  • One-Way Flow: The valve is designed to allow fluid to flow only in one direction. When pressure from the reverse direction occurs, the valve closes automatically to prevent backflow.
  • Prevents Contamination: It protects the water supply or system from contamination by preventing the reverse flow of potentially harmful substances.

• Size and Compatibility:

  • 3/4-Inch Size: The 3/4" check valve is typically designed to fit into systems with 3/4" piping. Ensure that the valve size matches the diameter of your pipe system for proper installation.
  • Threaded or Slip Connections: These valves often come with threaded (NPT) or slip connections for easy integration into various pipe materials like PVC, copper, or galvanized steel.

• Material Options:

  • Brass/ Bronze: Common for potable water applications due to corrosion resistance and durability.
  • PVC/Plastic: Lightweight and suitable for non-corrosive environments such as irrigation systems.
  • Stainless Steel: Highly durable and corrosion-resistant, ideal for high-pressure or harsh chemical environments.

• Types of Check Valves:

  • Spring-Loaded Check Valve: Utilizes a spring to close the valve when reverse flow is detected. These valves are compact and quick-acting.
  • Swing Check Valve: Features a hinged disc or "flap" that swings open when forward flow occurs and closes when reverse flow is detected.
  • Ball Check Valve: Uses a ball to block reverse flow and is commonly used in low-pressure systems.
