Product Detail

Product overview   

F43X manual sector blind valve is composed of left valve body, right valve body, middle valve body and connecting screw (three). Rotate the connecting screw with a wrench to make the left and right valve bodies complete the clamping and loosening action, and use the position change of the blind plate and the through-hole plate on the valve plate to achieve the purpose of opening and closing. It has the characteristics of simple structure, light weight, reliable performance and convenient operation.


This valve is a short structure series, and the rubber sealing rings are installed on the left and right valve bodies respectively.
