(R)EVOLUTION NEXT STEP

Quadruple butterfly valve

Over the years, there where made modifications for the centric butterfly valves, through the single eccentric, or double eccentric butterfly valve. Next changes were primarily to construct a butterfly valve characterized by high tightness and resistance to contamination and the priority was to reduce the problem of friction of the disc and seat. So in the 60s of the last century it was constructed the triple-eccentric butterfly valve. The patent of the quadruple-eccentric structure and what is associated with it as well as the new production technology is the next step in the evolution of the eccentric butterfly valves and a novelty in the global market. The quadruple-eccentric butterfly valve type QUADAX contains all the benefits of triple eccentric butterfly valves and in the same time eliminates their disadvantages.

APPLICATIONS:

Butterfly valves are approved i.e. TA Luft II, NACE MR 017, NACE MR 0103, certificate for oxygen BAM, 94/9 ATEX, Fire Safe and are manufactured according to DIN and ANSI. They have a wide range of applications, from installations of LNG and LPG to petrochemical industry, cryogenics, paper industry, mining, heating and power engineering.

Triple offset - An elliptical, small seat shape in the valve body is results of round cone.

Quadruple ( four offset ) - A round and bigger seat shape in the valve body is the results of an elliptical cone.
