PRODUCT CATEGORIES DESCRIPTION
A check valve, also known as a non-return valve or one-way valve, is a type of valve that allows fluid or gas to flow in only one direction. The design of a check valve includes a movable disk or diaphragm that opens when the fluid or gas flows in the desired direction, but closes when the flow reverses.
Check valves are commonly used to prevent backflow, which can occur when pressure changes or flow direction is reversed. They are widely used in various industries, including oil and gas, chemical processing, water treatment, and HVAC systems.
Check valves are available in different sizes and types, such as ball check valves, swing check valves, and lift check valves. They can be connected to piping systems through different means, such as threaded, flanged, or welded connections.
The size of check valves typically ranges from 1/2 inch to 12 inches, although larger sizes are also available for specific applications. The selection of a check valve depends on factors such as flow rate, pressure, temperature, and media type.
In summary, check valves are essential components in many fluid and gas systems. They provide reliable and efficient protection against backflow and help ensure safe and efficient operation of piping systems.
