Cam-Set
The Cam-Set (Model 81 FC) is a swing type of quick acting line blind. It has a three bolt design and a triangular body. It is appropriate for applications that require fast blinding turnaround and that do not exceed 1500# pressure class. It can be made as a standard design up to 48 inches (DN 1200).

Cam-Set Operation
Thanks to its revolutionary Cam design the spectacle plate can be locked into place or released in seconds. The plate can then be rotated or swung from left to right with ease. For larger size lines 12 inches and above the Cam-Set can be equipped with a counterweight, making plate position changing even easier.
Purpose
The primary Purpose of a swinging line blind is to completely close off the downstream portion of a pipeline in a quick and safe manner. Generic uses are:
- To guarantee safe operating conditions for maintenance procedures
- To enable quick line shut down in emergency circumstances
- To help prevent product cross contaminations in tank farms or ocean going tankers
- To avoid pollution due to valve leakage
