Covna valves use high-hardness materials, such as alloy steel and ceramic coatings, to resist wear caused by high-speed water flow and particles. These materials significantly extend the service life of the valves. In high-pressure water flow applications, Covna valves have a wear rate 50% lower than conventional valves, reducing replacement frequency and maintenance costs. Covna valves are cost-effective and reliable solutions for high pressure system applications.
