Kelva brakes are designed for many different applications. Our three brake sizes, all of which can be equipped with high or low friction pads, cover braking requirements for a wide variety of materials.
As they are pneumatic and therefore explosion-proof, they can be used in conditions where electrically operated brakes would be unacceptable.
KELVA Web Tension Control
Kelva LV9 consists of a pneumatic regulating valve with a cylinder arm or spring arm. The device is fitted to a round bar, with its roller against the reel of material.
It registers reduction in the diameter of the reel and regulates the air pressure to a Kelva brake accordingly so that web tension is held constant.
