Types of Check Valves

Check Valves Manufacturer

Various types of Check Valves are used in various applications. These include Cast steel, Rubber, and Wafer. These types of Check Valves have applications in industries such as Oil and Gas, Water, and Food.

Rubber

Depending on your application, there are different types of check valves available. They are used to maintain the flow of liquids in systems. They are commonly used to maintain the flow of water, as well as sewage and water treatment systems. They prevent backflow and are a great way to maintain system reliability.

Cast steel

Unlike forged valves, cast steel valves are made by a casting process. Casting is the process of melting metals into a molten liquid and then poured into a mold to form a valve. Casting can produce complex shapes and sizes. Cast steel valves are used in a wide range of applications, including industrial and process industries.

Wafer

Compared to other types of valves, wafer check valves are very small and thin. They are suitable for systems where the flow of fluid is controlled in a single direction, eliminating the risk of reflux within the system. They are available in two-piece or spring-loaded types.

These valves are made of various materials, such as stainless steel and brass. They are suitable for applications in the chemical process, water and wastewater treatment, waste treatment, and system engineering industries. They can be installed in both horizontal and vertical piping systems.

Swing

Various kinds of materials are used for swing check valves. For example, brass swing check valves have a unique construction. These valves provide smooth flow passage, and are safe for different applications.

These valves are typically used in the oil refinery, water treatment, and wastewater treatment industries. They are also used in power generation. They are important for dependable fluid system operation. However, they can suffer from leaks. They need to be installed properly to prevent leakage.

Bronze

Whether you need a check valve for a water treatment application or for a chemical process, there are many different types of valves available to choose from. They are made of various materials, such as stainless steel, bronze and ductile iron. These valves are available in a variety of configurations, including ball, disc, duckbill, flange, and globe.

Inlet and outlet ball

Generally, a check valve is a device that automatically opens and closes to prevent backflow. It is activated by a pressure difference between the inlet and outlet pressure. They are available in different designs and sizes. They are often used for applications such as water and wastewater treatment, industrial, and chemical processes.

Oversizing

Having a properly sized check valve is a great way to keep costs down and increase the longevity of your system. Oversized check valves can cause a variety of problems, including valve chatter, choked flow, and increased stress. These problems can cause additional costs and downtime.

Having a properly sized check valve can also help you avoid the dreaded water hammer. This is a condition in which the upstream pressure is lower than the downstream pressure. It can cause the valve to chatter and flutter. When this happens, it can lead to premature wear and tear on the valve and its surrounding components, as well as more downstream damage.

Applications in the industrial sector

Flow control applications of check valves are a common solution to preventing backflow in a variety of industrial applications. Check valves are also called one-way valves and are used to regulate the flow of liquids and gases. Check valves are a cheap, easy-to-deploy solution to backflow that can prevent damage to equipment and waste materials.
