Throttle valve type LINA

The regulating valve LINA has been specially designed by us for ventilation systems according to DIN 24154. Despite its light and compact design, we have taken great care to ensure that it meets the requirements of industry to the highest degree. Depending on the material combination, LINA can therefore be used safely in your plant for extreme control tasks (high temperatures, aggressive media, etc...). Due to its modular welded construction, LINA can be quickly modified by us to suit your particular application. Like all our butterfly valves, LINA also has an integrated ISO interface and is supplied ex works with corrosion protection.
