China Check Valves manufacturers Introduction The Brass swing type check valve is a valve that only allows fluid to flow in one direction. The check valve has various structures, and different structures have different functions. The top of our product is the bonnet part. The valve cover is fixed to the valve body through a series of bolts at the edge and sealed with gaskets. A bolt is installed in the center of the valve cover for installing the pressure gauge or vent valve. When the fluid pressure at the inlet increases, overcoming the weight of the valve disc and the fluid pressure at the outlet, the valve disc will open. As the pressure increases, the disc will gradually reach the fully open position. Features Brass swing type check valve can generally be used on various pipelines with operating temperatures in the range of - 196~540 鈩? By selecting different materials, it can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium, urea, and other media. Its most significant advantage is that the pressure drop between the inlet and outlet of the valve is very low, so this valve is very suitable for high-flow rate and low-flow-rate applications. Not only that, but the turbulence generated by the fluid passing through the valve is also very small. If the valve leaks, you can directly replace the seat ring, disc, and other parts.
