Back flow dampers

• Chemical resistance to aggressive mediums
• Light weight, simple assembly
• Long service life
• Good leak resistance
• Lower service costs (smooth surfaces don’t accumulate sediments)
• Environment protection, products are recyclable.

The wall thickness of muff connection is always equal to wall thickness of back-flow damper.

Note! On special request we can make the wall thickness of back-flow damper and of flange connections thinner or thicker.

TYPES OF DAMPERS’ CONNECTION
