F43CX manual fan-shaped blind plate valve

F43CX manual fan-shaped blind plate valve, also known as manual spectacle valve, flip plate valve and fan-shaped valve, is a long structure series with a telescopic device on the right body, which can be used in long lines (injection: can not be used as a compensator for the pipeline). It can compensate the axial displacement of the valve body during the valve opening and closing, and reduce the opening and closing moment of the valve. According to the characteristics of large caliber valves, the valve body is designed as a triangular structure, which strengthens the overall rigidity of valves. The rubber sealing rings are installed on the left and right valve bodies respectively.
