Wafer Type Check Valve is a type of valve that is used to regulate the flow of fluids in pipelines. It is designed specifically to prevent backflow, which is the unwanted reversal of fluid flow. This type of valve is ideal for use in applications where flow reversal can cause serious damage, such as in chemical, pharmaceutical, and oil and gas industries.

The valve is designed to fit between two flanges and has a circular disc that swings on a hinge to allow flow in one direction and block flow in the opposite direction. The valve works by using the pressure of the fluid to push the disc against the valve seat, which creates a seal and prevents backflow.

Wafer Type Check Valves are available in a range of materials, including stainless steel, carbon steel, and PVC, to suit different applications. They also come in a variety of sizes and pressure ratings to accommodate different flow rates and system pressures. This makes them a versatile and reliable choice for any process application.

One of the main advantages of Wafer Type Check Valves is that they are compact and require minimal space, making them ideal for use in limited-space applications. They also have a simple and low-maintenance design that ensures long-lasting operation and minimal downtime. Additionally, they offer high flow capacity and are able to handle a wide range of fluids, including gases, liquids, and steam.

In summary, Wafer Type Check Valve is a reliable and versatile solution for preventing backflow in pipelines. They are available in a range of materials and sizes to suit different applications and offer a range of benefits, including compact size, simple design, and low maintenance.
