Manual Manifold Bottom Loading Style

PRACTICAL. WROUGHT MATERIAL. FABRICATED CONSTRUCTION. GREATER VERSATILITY

The Betts bottom loading manifold is a practical means of providing connections to bypass the manifold during bottom loading, and yet, it is an integral part of the manifold. By making bottom loading connections integral with the manifold, additional gasket joints are eliminated.

Body is wrought steel or aluminum. Fabricated construction allows for custom design, which provides greater versatility and simplifies piping layouts.

PRESSURE & TEMP. RATING: 5 PSI MAWP at ambient temp.
