Stainless steel Dual plate check valve

The stainless steel wafer dual plate flap check valve adopts a new type of corrosion-resistant stainless steel. It can be installed on the pipeline at any position to prevent the medium from flowing back, and the boiler water supply system is back-up. The connection method is to use the original pipeline at both ends of the flange to be clamped and then put into operation. Its various indicators are better than any kind of upper return valve currently on the market. It has a wide range of applications, including water, gas, oil, acid, lye, hydrogen, ammonia, special fire-fighting pipelines and other media.
