There are many different types of check valves. They can be Ball, Butterfly, O-ring, or swing. To find the right one for your needs, it helps to know a little about the different types. This article covers the basics of these different types. If you have a question, don’t hesitate to ask our customer service department. They are available around the clock to help you get the right part for your needs.
Ball check valves are used in a wide range of applications. They are generally made of thermoplastics or fiberglass, with full-length ribs for maximum flow and minimum pressure drop. They also have a molded gasket seal, making maintenance easier and more efficient. They are available in a range of sizes, from 1 to 10 inches, and are suitable for applications including water, fertilizers, oil, irrigation, and pharmaceuticals.
Butterfly check valves are used in a variety of industries. They can be used for a variety of fluid control applications, including chemical processing and wastewater treatment. A variety of valve manufacturers have been in business for many years. Several have a global presence and focus on several market segments.
O-rings are the seals that keep a check valve closed. The material used for these seals is important because it affects the flow of fluids. Fortunately, a quality O-ring will ensure that the valve stays closed even when the pressure inside it is extremely high.
A swing check valve opens when a liquid hits it and closes when the flow reverses. It works with a disc and hinge attached to its seat. This design allows for a small cracking pressure and large flow capacity. The valve’s reversal function assists the closing action and prevents backward flow.
A PVC check valve is a type of valve used to prevent the backflow of liquids and gases in a line. They feature an opening and closing member that is activated by the flow of the fluid.
Brass check valves are designed for use in various industrial applications. They are available in both vertical and horizontal configurations. It is necessary to select the right valve size according to the needs of the project. When selecting the right size, it is vital to check whether the valve is sized according to the API 6D standards.
The primary material used for check valve construction is aluminum-bronze. This material has excellent weldability and castability. It is also corrosion-resistant, making it a good choice for use in seawater.
A plastic check valve manufacturer can provide a variety of types of check valves for different applications. These valves are available in different materials, including PVC, CPVC, PVDF, and polypropylene. Some models also have features such as EPDM O-rings or a true union design. These types of valves can be used in a variety of industries, including water treatment, power generation, pulp and paper, and chemical drainage.
