Swing-type flange check valve mainly uses a cast steel valve body and is designed for one-way opening and closing to prevent backflow of media in various equipment. The swing-type flange check valve opens or closes automatically based on the pressure of the medium and can only be installed vertically, not horizontally. It is suitable for clean media but not for media containing solid particles or with high viscosity.
