The MS Wafer Type NRV (Non-Return Valve) DN 150 is a swing-type non-return valve designed for preventing backflow in fluid systems. Its wafer-style body enables installation between two standard flanges without the need for extensive space or extra fittings.

This model features a Mild Steel (MS) body for structural integrity, a Ductile Iron (DI) disc with Nickel Plating (NI) for corrosion resistance, and a Stainless Steel (SS) stem, ensuring reliable and long-lasting operation in various industrial and fire protection systems.

he MS Wafer Type NRV (Non-Return Valve) is a compact, lightweight, and efficient valve designed to allow flow in one direction and prevent backflow in pipelines. This model, with a DN 80 (3") nominal bore, is ideal for applications in water, HVAC, fire protection, and general industrial systems.

The disc is made of Ductile Iron (DI) with Nickel Plating (NI) for corrosion resistance and durability, while the stem is constructed from Stainless Steel (SS) for strength and wear resistance. The wafer design allows easy installation between flanges, saving space and weight compared to flanged types.
