One operator turns handwheel and unique gear-set mechanism makes a gap without pipe spreading. By Sliding Blind plate manually, Open/Close Blind position is changed. All blinding process completes within 3 minutes safely and easily. Sturdy and simple design shall make high reliability with the most advanced technology and durability.
READ MOREIt take within 3 minutes for one operator to blank a line, operating the handwheel and rotating the blind into place without line spreading. Again, all inline movement is internal, eliminating the potential for pipe-joint stress. As one of the most popular model, quick operation with no line spread and correct spectacle positioner shall make easy and safe pipe line isolation.
READ MOREThe Compact type is designed for replacement of existing valves, limited F-F dimension or large diameter pipeline applications or limited space for installation. It is designed with a short face to face, and has tapped bolt holes for easy installation between flanges. The compact design also reduces weight and requirement for extra pipe support.
READ MORENon spill type of Line Blind has good advantages in Oil terminal & offshore applications where is limited installation space and marine pollution is strictly prohibited. The 3 sides covered body & compact design prevents ground pollution and it allows to install at parallel pipe lines.
READ MOREThe traditional style of line blind offers a broad range of pressures and a lower cost. The basic standard for line blinding for many years. After turning 3~7 jack bolts around the body to make a gap by round bar or wrench and then change the blind plate position. Pipe line needs to be spreaded for operation.

READ MOREAutomated Line Blind Valves are used for remote control operation, freguence cycle, or critical fluid application Sammi provides automated system by AOV, MOV or oil hydraulic source.
READ MOREEX Line blind - offers 100% pipe isolation for severe services
such as extremely high temperature (816℃) / cryogenic condition (-196℃) or gas / liquid containedparticles / polymer applications.
The unique spreading mechanism makes a gap to switch blind plate position in a short time.
Only gasket replacement of blind plate is needed for maintenance.(No internal gasket).
