First, the product features

Manual blind plate valve, also known as manual glasses valve, flap valve, fan valve, for the long series of structures, in the right valve body with a retractor for longer pipeline (Note: not as compensator of the pipeline) , You can compensate for the valve opening and closing process of the axial displacement of the valve body, reducing the valve opening and closing torque. According to the characteristics of large-caliber valves, the valve body is designed into a triangular structure to enhance the overall rigidity of the valve. Rubber seals were installed on the left and right valve body.
