What is a Wafer Swing Check Valve?

A Wafer Swing Check Valve is a type of check valve designed with a thin, compact, and lightweight wafer-style body that fits between flanges. It utilizes a swinging disc to allow fluid flow in one direction and prevent backflow in the opposite direction. Its compact design makes it suitable for installations where space is limited.

What are the key features of the VINCER Wafer Swing Check Valve?

The key features of the VINCER Wafer Swing Check Valve include:

• Compact wafer design for space-saving installation.
• Swinging disc for reliable backflow prevention.
• Minimal pressure drop and streamlined flow path.
• Suitable for horizontal and vertical installations.
• Lightweight and easy to install.
• Durable construction with low maintenance needs.

What is the working principle of the VINCER Wafer Swing Check Valve?

The VINCER Wafer Swing Check Valve operates using a swinging disc. When fluid flows in the intended direction, the disc swings open, allowing fluid to pass through. If the flow reverses, the disc swings back onto the seat, blocking the flow and preventing backflow. This action is assisted by gravity and the reverse flow pressure.

What material options are available for the VINCER Wafer Swing Check Valve?

The VINCER Wafer Swing Check Valve is available in several material options, including:

• Carbon Steel
• Stainless Steel (304, 316)
• Alloy Steel
• Cast Iron
• Ductile Iron
• Bronze

Differences Between Wafer Lift Check Valves and Wafer Swing Check Valves

1. Design and Operation:
   • Wafer Lift Check Valve: Utilizes a lifting disc that moves vertically within a guide to allow or block fluid flow. The disc lifts off the seat with forward flow and drops back to the seat when the flow reverses.
   • Wafer Swing Check Valve: Utilizes a swinging disc that moves to allow or block fluid flow. The disc swings open with forward flow and closes when the flow reverses.
