Non Return Valve Supplier
A Non-Return Valve (NRV) is designed to allow fluid to flow in one direction only, preventing backflow. Kaizen Steels is a top manufacturer and supplier of these valves, offering a range of materials to suit various needs, including bronze and stainless steel. The SS Non-Return Valves are available with different flow rates such as 93, 2.34, 6.42, and more, providing options for various applications.
Non-return valves, also known as check valves, allow fluid to flow in only one direction, preventing backflow. At Kaizen Steels, we manufacture and supply a variety of non-return valves made from materials like stainless steel and bronze. The SS 304 non-return valves, with thread types such as BSPP and C.61 4-bolt flange, are ideal for general corrosive environments due to their durability and corrosion resistance. For more demanding conditions, SS 316 non-return valves are preferred because of their enhanced resistance to corrosion.
Our valves operate at various pressures, with most rated up to 3000 psi. The different sizes, such as the 1/2-inch stainless steel non-return valve, cater to diverse fluid flow systems. One of the most popular types is the wafer non-return valve, widely used across industries. We also offer flanged and screwed-end versions, each suited for specific applications.
