Statotherm V Cover seal V901/…

Features

Statotherm V Cover seal V901 rings are high precision seals, which give a very good sealing result with excellent service life combined with very little wear.
They are made from permanently elastic, expanded graphite (>99% graphite) without binders or fillers.

Advantages

Statotherm V Cover seals V901 are used as self-sealing gaskets in high-pressure valves e.g. for power plants at high temperatures and up to approx. 1,000 mm diameter
They do not harden, have a long service life and can easily installed and removed without damaging the seal surface, as can happen with metallic seals
