Features
The F43X Manual sector blind valve is composed of a left valve body, a right valve body, a middle valve body, and three connecting screws. Rotate the connecting screw with a wrench to make the left and right valve bodies completely clamp and loosen. The position of the blind plate and the through-hole plate on the valve plate is changed 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 ring is installed on the left and right valve bodies respectively.
