Econ® Line Blind


Econ® line blind valves are specially designed to separate pipelines and storage tanks for 100% (segregation). The excellent quality guaranties a safe, reliable and environmentally friendly solution. This in contrary to the use of blind plates and “spectacle line blinds” which is labour-intensive and will always cause loss of medium. Due to its quick open- and closing mechanism Econ® line blinds are easy to operate and the two combined discs - also called JoJo- can be removed or installed safe and free of leakage.
