Cast Iron Butterfly Type Check Valve

Wafer end swing check valve is mainly composed of three parts: body,  disc( stem),  spring. The short closing stroke of disc and the spring force improve the closing effect,  while also reduce the pressure surge  and  slamming noise.

Main feature:

The valve body passageway is designed in a wing-shaped streamline type, allowing the medium to flow through the passageway rapidly and steadily with no noise. It is opened or closed by the valve clack moving to-and-fro through the valve body guiding axle under the spring effect. It can be installed on horizontal and vertical pipelines.

Advantage

Two arch disc are fixed onto the valve body with a spindle on which two torsional springs are equipped for installing the butterfly plate onto the valve body sealing face. The butterfly plate pressed by the springs is opened by relying on the medium pressure, and the valve is closed by the spring force and the medium pressure under backflow. It can be installed on horizontal and vertical pipelines.
