This type of three-point quick switching blind plate is suitable for blind plate plugging operations in large-diameter and low-pressure pipelines. Only one staff member needs to operate the electric actuator to loosen the left and right valve bodies, and rotate the plate into place. It takes 3-5 minutes to complete the blind plate plugging operation for large-diameter pipelines. Electric, pneumatic and other different actuators can be selected according to on-site requirements to replace manual safety and efficiency.
