Check Valves

Check valves, also referred to as non-return or one-way valves, are essential components in various fluid systems designed to allow the flow of gases or liquids in only one direction. Generally utilised in industrial and residential settings, these valves are crucial for stopping the backflow of fluids, which can cause damage or contamination to the system. Check valves are typically made using a variety of materials, including brass, stainless steel, and PVC, which are selected based on the specific media and environmental conditions of their application. They maintain consistent operational efficiency and ensure safety by preventing reverse flow, which is crucial in applications like water treatment and chemical processing.
