Butterfly Valve Type GD-6 – Standard design
General:
JASTA´s butterfly valve of the type GD-6 is a valve that is clamped between flanges. Thanks
to the diversity of available materials, this valve can be employed in almost all media and
industry sectors. Its functionality is, however, not restricted to one control- or throttle function:
using the variant of the highest density shows a leakage rate of only 0.02% of Kv 90°.
Particularly in case of high temperatures in the low-pressure area and also with regard to
many other fields of applications, this “shut-off function” ensures high efficiency, so that the
use of much more expensive double- or triple eccentric shut-off valves becomes superfluous.
Fields of applications:
Melting plants, foundries, cement mills, crematories, industrial furnaces (for iron, steel,
aluminium, stainless steel), glassworks, plants (for Rockwool, gas concrete etc.), ceramic
furnaces, drying- and dust removal installations, gas turbines, annealing systems, high
temperature furnace engineering etc.
Specification (standard design)
Customized solutions and modifications are available. Please enquire separate.
