Section 5<br />

Mixproof Valves<br />

<strong>GEA</strong> <strong>Tuchenhagen</strong> mixproof valves provide safe, reliable<br />

separation of incompatible liquids between intersecting<br />

pipe lines.<br />

5<br />

Based on the principle of three single seat valves in a double<br />

block and bleed arrangement, the mixproof valve comprises<br />

an upper and lower valve seat and a cavity between them which<br />

provides a leak path to atmosphere.<br />

In the event of gasket failure at either<br />

seat, pressurized liquid leaks<br />

into the cavity and will drain<br />

freely to atmosphere via the<br />

cavity without danger of<br />

breeching the seat gasket of<br />

the intersecting pipe line,<br />

preventing contamination<br />

of its contents.<br />
