There are several methods to blank a line. The most common include using Blanking flanges and spools o r Spectacle plates and gaskets between flanges. Using either of these methods has several disadvantages:
In short the procedure of traditional blanking is time consuming, inconvenient, costly and can be dangerous.
The advent of fast acting line blinds such as the Cam-Set and Cam-Slide made it simple to blind a line quickly, from one side of the line by a single operator. They are sometimes referred to as fast acting line blinds, Hamer blinds or line blind valves.
At it's most simple level, the Cam-Set and Cam-slide is a mechanism that enables a spectacle plate to be changed from open to closed in less than 60 seconds.
The part that enables this is a Cam System which creates space for the plate to move and then to be securely locked in place. The cam system is actuated via a stem connected to a hand wheel. No bolts need to be removed; simply turn the hand wheel, and swing the plate to the new position. Then turn the hand wheel again to lock it back into place.
Safe, Fast and Convenient
The Key advantages of this system are:
