Cam-Slide
The Cam-Slide (Model 81 CS) is a sliding quick acting line blind. It has a multi bolt design and a rectangular body. It is appropriate for applications that require fast blinding turnaround up to 2500# pressure class. It can be made as a standard design up to 64 inches (DN 1600).

Cam-Slide - Sliding line blind
Design & Operation
Its multi bolt design enables a more compact build and lighter weight which make it ideal for tight spaces with reduced face to face dimensions. The Cam-Slide is also available as a non spill line blind.
The Cam-Slide utilizes the tried and tested Cam design. This ensures that the spectacle plate can be locked into place or released in seconds. The plate can then be moved in a sliding motion from left to right and vice versa with ease. For larger size lines 12 inches and above the Cam-Slide can be equipped with a gearbox or electric actuator, making plate position changing even easier.
A special High Temperature Cam-Slide design is also available for processes that require to withstand temperatures over 327 degrees C.
