The SHENGFEI Fire Safe High Performance butterfly valve has a primary PTFE and a secondary fire safe SS316 seat (INCONEL seat is also available).
In case of fire the PTFE will melt and keep the secondary seat shut. The preferred direction ensures a long service life. A floating seat construction makes the shutdown 100% bi-directional.
On request we provide assembly drawings, 3D CAD models and engineered solutions.
SHENGFEI implementing a robust quality management system compliant to ISO 9001-2015. API607 Fire-safe certified. These certificates guarantee the quality of our high performance butterfly valves.
