CAST IRON BUTTERFLY CHECK VALVE
Butterfly Check valve 19ch21r is used to prevent the reverse flow of process fluids. The body material is GGG40 cast iron, an analogue of HF40. Installation is carried out on utility lines with water and non-aggressive media. The product is not susceptible to temperature changes up to 110 ºC. The method of connecting to the pipeline is wafer. This means that the installation is carried out with a tie between two flanges. The valve consists of two nickel plated discs connected by a spring. This design prevents reverse movement of the working medium.
