Cam-Set
The Cam-Set (Model 81FC) is a quick acting swing type 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.
Features
- Simple operation – one person, one side, no bolts need to be removed
- Can be operated in less than 30 seconds
- Available in sizes up to 48 inches and ASME 1500#
- Nonline spreading
- Man Safe – 100% positive isolation
- Seals not affected by piping misalignment
- Conforms to or exceeds many safety and engineering standards
Options
- A broad range of sealing rings to match the specific medium and operating conditions including the most common – Viton, Kalrez, Aflas, EPR/EPDM, Silicone, etc.
- Stem and dust covers for powder applications or dusty operating environments
- Lock out devices
- Pneumatic, electric or manual actuation
- Filter, rupture disc or sieve integration in the spectacle plate
- Drain, vent and purge connections
- Special anti corrosive or medium driven coatings or linings (such as Sermetal, Epoxy, PFA or ceramics)
- Reinforced designs for challenging operating environments
