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.Main performance indicators
