Cast iron non-return valves are what we are working on currently. It is a kind of valve that controls fluid flow, usually in plumbing or HVAC systems. In addition, the range that is offered is made to only permit one direction of fluid flow in order to prevent backflow. Cast iron is a strong, corrosion-resistant material that can tolerate high pressure and temperatures, and is often used to make cast iron non-return valves. It frequently works in tandem with pumps, filters, and other fluid handling machinery.
