The manual blind plate valve is composed of a left valve body, right valve body, and connecting rods (three pieces).
The clamping and releasing actions of the left and right valve bodies are accomplished by rotating the connecting rods with a spanner. This changes the position of the blind plate and allows the valve to be opened or closed.
This product features simple structure, light weight, good sealing performance, and convenient operation.
In this short-structure series, rubber sealing rings are mounted separately on the left and right valve bodies.
