Product details
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.
