Weir Firesafe certifed Double Offset High Performance
Valve,available Class 150 -900. Valve is available with Varidiff
Trim, if cavitation is a problem. Designed to
meet the stringent safety requirements of the offshore industry,
the Firesafe Valve is also being widely used in other areas; such
as chemical plants. Whilst utilising many of
the proven design features of the Hyperseal Valve in its
construction, the Firesafe Valve has a two tier sealing
arrangement. The primary ‘PTFE’ seal is backed up by a
secondary metal seal ring. Should elevated temperatures result in
the destruction of the ‘PTFE’ seal then the shut-off integrity of
the Firesafe Valve is maintained by the metal sealing
ring.
The Firesafe Valve has been tested and approved to
BS6755 part 2, API 6PA, 6D and 607, and is available in the same
size and pressure ratings as the Hyperseal Valve.
