Product overview

HH47/H47XF/HDH butterfly buffer check valve is mainly used at the pump outlet of industrial water supply and sewage treatment plant to prevent the reverse flow of medium in the pipe network. Automatically eliminate destructive water hammer, so as to ensure that the water pump and pipeline are not damaged. The valve is mainly composed of valve body, valve disc, buffer device and micro regulating valve. The product has the characteristics of novel structure, small volume, small fluid resistance, stable operation, reliable sealing, wear resistance and good cushioning performance. It is the best product for industrial water and sewage.
