SaundersWFB TypeValves
ForMarine and FirefightingApplications
TheWFB valve is a weir type diaphragm
valve developed to overcome conventional
valve problems on fire fighting, tank cleaning
and wash-down on land or sea, wherever
guaranteed valve operation is needed.
There are no second chances with a defective
fire hydrant valve. SaundersWFBmodel
provides dependable operation when it matters
– even after years of non-use.
This highly specialised fire hydrant valve has
been tested and approved by the world’s
leading safety agencies. Similar in design and
operation to the widely used A Type, it has the
added benefit of a certified chlorosulphonated
polyethylene base fire resistant diaphragm. The
WFB valve is available in SG iron or gunmetal
providing highmechanical strength. This means
that they provide greater resistance to
accidental impact. Gunmetal resists corrosion
on the more demanding applications.
