Gosco Valves: Designs That Outperform.

Gosco’s M-Class & S-Class valves (On/Off, Vari-V, Cryogenic, FM) are now API 607 5th Edition approved.

API 607 5th edition was released in June 2005. It is a joint standard with ISO and is titled, “FIre Test for Soft-seated Quarter-turn valves, ANSI/API Standard 607, Fifth Edition, June 2005, ISO 10497-5:2004 for “fire type-testing requirements”. The basic test parameters are similar to API 607 4th edition with some changes to the probe locations and qualification of other sizes/pressure classes/materials.
