What is Disc Check Valve? Properties, Uses and Application

Disc Check Valve

Disc check valves are essential in various industrial applications such as petrochemical processing, oil and gas pipelines, water treatment plants, and numerous other industries. They are designed to ensure fluid flow in one direction while preventing pipeline backflow. In this blog post, we’ll delve into disc check valves’ properties, uses, and applications and how to use them effectively.

What is Disc Check Valve?

A disc check valve is a type of non-return valve which uses a sliding disc to prevent fluid or gas from flowing in the reverse direction. It consists of a disc, hinged at one end and connected to a stem, with spring action to keep the valve closed. When pressure on one side exceeds the other, the disc opens, and media passes through. The full opening of the valve occurs when the pressure differential is sufficient to lift the disc off its seat.

Properties of Disc Check Valves

Disc check valves are usually made of different materials, such as stainless steel, brass, plastic, and cast iron. They come in several types: dual plate, wafer check, and swing-type valves. They are highly efficient and can operate at high pressures and temperatures. Their simple design and low maintenance make them a popular choice in industries worldwide.

Uses of Disc Check Valves

Disc check valves are commonly used in various industrial processes, such as regulating flow in water treatment plants, oil and gas pipelines, and HVAC systems. They are also used in fuel and chemical processing, marine, and power generation industries. Other uses include processing food and beverages, pulp and paper, and pharmaceuticals.

Applications of Disc Check Valves

Disc check valves are versatile and used in several applications, such as preventing water backflow in sump pump systems, sewage ejectors, and wastewater treatment plants. They regulate flow in fire protection, steam boilers, and cooling systems. They are also used in oil and gas pipelines to prevent unwanted backflow.

How to Use Disc Check Valves

Proper installation and maintenance are essential to using disc check valves effectively. Before use, inspect the valve thoroughly and ensure the correct installation. Disc check valves are installed horizontally or vertically on the pipeline. Maintenance involves routine checks for corrosion and wear; replace the valve immediately if damaged. Regular cleaning is also important to avoid clogging.


Disc check valves are essential components in controlling fluid flow in industries worldwide. Their properties, uses, and applications make them ideal for numerous operations. Proper installation and maintenance ensure the effective use of these valves. Knowing the basics of disc check valves is crucial whether you are in the engineering, manufacturing, or maintenance field. This blog post has given you a better understanding of disc check valves and their effective use.
