Key Features:

1. Single-Plate Design:

   • The valve uses a single disc or plate that pivots or moves linearly to open or close, depending on the flow direction.

   • The disc design ensures minimal resistance to flow when open and provides a tight seal when closed.

2. Wafer-Style Construction:

   • The valve is designed to fit between two pipeline flanges, eliminating the need for additional bolting or support.

   • This compact design saves space and reduces installation time and costs.

3. Low Pressure Drop:

   • The streamlined design of the disc and valve body minimizes turbulence and pressure loss, ensuring efficient flow.

4. Quick Response:

   • The lightweight disc allows for fast closing, reducing the risk of water hammer and protecting downstream equipment.

5. Durable Materials:

   • Constructed from high-quality materials such as stainless steel, ductile iron, or carbon steel, the valve is designed to withstand high pressures, temperatures, and corrosive environments.

6. Bidirectional Sealing (Optional):

   • Some single-plate wafer check valves are designed to provide sealing in both directions, making them versatile for specific applications.
