Line blinds designed for total shutoff of the process pipelines commonly found in oil, gas, petroleum, and chemical applications are available in sizes from 1 to 24 in. and in pressure ratings to ANSI Class 600. They do not require the movement of adjacent piping when the blind's position is changed from open to closed. They also accommodate rapid operation by a single person from one side of the piping. They are available in various materials of construction as well as with flanged ends, BWE, and special ends to meet customer requirements.
