About this document

ANSI/FCI 70-3 Seat Leakage Classes by Shabir Khan is a document available to read on EtoBox.

This document outlines 7 seat leakage classifications (I-VII) in accordance with an industry standard for valves and regulators. It describes the maximum permissible leakage for each class based on factors like the type of valve (double-seat metal vs single-seat metal vs resilient sealing) and whether testing is at maximum operating pressure. It also provides a table specifying leakage rates in ml/min corresponding to nominal port diameters from 1 to 16 inches to define Classes VI and VII.
