Structural features and uses:

The valve DN300-800-type manual fan-shaped blind valve for the long structure series. The valve in the right valve body with expansion joints, generally used in longer lines.

The valve of the telescopic valve opening and closing valve can compensate for the axial displacement of the valve to reduce the opening and closing torque (Note: can not be used as a pipeline compensator)

The valve DN900-1400-type manual fan-blind valve for the long structure series. The valve is equipped with a telescopic device for a longer pipeline (Note: can not be used as a pipeline compensator). According to the characteristics of large-diameter valve, the valve body designed into a triangular structure, to strengthen the overall rigidity of the valve.
