The SAMMI Line Blind valves incorporate a simple and durable design that provides absolute shut-off, zero leakage, and long-lasting, cost-efficient service with minimal maintenance. Its unique opening-closing mechanism allows one untrained operator to quickly and safely blind pipelines without any tools or equipment. The system ensures easy and safe blinding, minimises pipeline stress during operation, and features a non-self-sticking mechanism to prevent the blind plate from sticking. Cost-saving benefits include reduced maintenance hours and man-hour costs, while the hand-wheel operation eliminates the need for additional tools. Additionally, the SAMMI Line Blind valves satisfies health and safety legislation, preventing potential hazards such as inhalation of toxic fumes, spills, and explosion risks. Its simple structure requires only the replacement of sealing components, and the friction-free gear-set system provides perfect isolation without contact or rubbing.

SLIDING TYPE Sliding type line blind has a unique gear set mechanism that makes a gap to slide in/out a blind plate without pipe joint stretching. It provides a safe and time efficient blinding process. SAMMI Line Blind valves have a sturdy and simple design creates highly reliable and durable line blinds using the most advanced technology. SWING TYPE Swing type line blind is one of the most popular line blinds that an operator can use to quickly and efficiently isolate a pipeline safely. SAMMI Line Blind valves have a unique design provides non-stretching operation that can prevent pipe joint stress caused by stretching movement. COMPACT TYPE Compact type line blind is designed for replacing an existing valve with limited F-F distance, large diameter pipeline or limited space installation. SAMMI Line Blind valves have a compact design provides weight reduction and removes the need for extra pipe supports. NON-SPILL TYPE Non-Spill type line blind has many advantages in oil terminal and offshore applications where the space of installation is limited and prohibiting of pollution is strictly required. With the SAMMI Line Blind valve unique design, this line blind can prevent ground pollution and be installed parallel to the pipeline. JACK BOLT TYPE Jack Bolt type line blind has been used for a long time as it is applicable for a broad range of pressure pipelines with a lower cost. To change the blind plate position, an operator is required to unbolt it manually. GOGGLE TYPE Goggle type line blind is a good solution to isolate large diameter, high temperature and/or toxic gas pipelines for maintenance and inspection. AUTOMATED LINE BLIND Automated Line Blind is good for remotely controlled blinding operation, high frequency of on-off cycle and/or critical fluid application. SAMMI Line Blind valves provide automated blinding system by AOV, MOV or oil hydraulic source. EX TYPE EX type Line blind offers 100% pipe isolation for severe service conditions such as extremely high temperature, cryogenic, gas/liquid contained particles and/or polymer production pipeline. The unique stretching mechanism creates a gap to switch blind plate positions quickly and efficiently.
