Detail Information
Carbon Steel Line Blind Valve ASTM F1020-86
Product Description
The Cam-Slide is a sliding type line blind where the blinding plate travel is linear, compared to the swinging motion of the Cam-Set. The Cam design allows for quick and smooth position changing. The Cam-Slide features a multi-bolt design allowing for convenient operation with more compact face to face dimensions. The additional body bolts make this style ideal for higher pressure applications.
Features
1. Man Safe – 100% positive isolation;
2. Compact design for tight fit applications;
3. Available in sizes up to 64 inches and ASME 2500#;
4. Non line spreading design;
5. Simple operation – one person, one side, no bolts need to be removed;
6. Conforms to or exceeds many safety and engineering standards.
