There are six different seat leakage classifications as defined by ANSI FCI 70-2. The most commonly used by Gemco Valve are CLASS I, CLASS IV and Ansi fci 70 2 pdf Vl.

CLASS I is also know as dust tight and can refer to metal or resilient seated valves. CLASS IV is also known as metal to metal. It is the kind of leakage rate you can expect from a valve with a metal shut-off disc and metal seat. CLASS Vl is known as a soft seat classification. Soft Seat Valves are those where the seat or shut-off disc or both are made from some kind of resilient material such as Teflon.

ANSI FCI 70-2 superseding ANSI B16. Pressure applied to valve inlet with outlet open to atmosphere or connected to a low head loss measuring device full normal closing thrust provided by actuator. Max service pressure drop across valve plug, not to exceed ANSI body rating. Pressure applied to valve inlet after filling entire body cavity and connected piping with water and stroking valve plug closed. Use net specified max actuator thrust, but no more, even if available during test. Allow time for leakage flow to stabilize. Class VINot to exceed amounts shown in following table based on port diameter.

50 psig or max rated differential pressure across valve plug whichever is lower. Actuator should be adjusted to operating conditions specified with full normal closing thrust applied to valve plug seat. Allow time for leakage flow to stabilize and use suitable measuring device. Bubbles per minute as tabulated are a suggested alternative based on a suitable calibrated measuring device, in this case a 0. The tube end shall be cut square and smooth with no chamfers or burrs.
