Here are some of the most effective methods for fire protection butterfly valves:
Installation of automatic fire sprinkler systems around the valves.
The water discharge from sprinklers can provide cooling and wet down valves during a fire.
Application of intumescent fireproofing coatings to the valve body and disc.
These coatings expand when heated to create an insulating char layer.
Wrapping valve bodies with fireproof blanket materials such as ceramic fiber or silica cloth.
This protects the valve from direct flame impingement.
Use of thermal insulation blocks, pads, or wraps around the valve and adjoining piping.
This adds additional heat resistance.
Utilizing butterfly valves constructed from metals with high melting temperatures such as stainless steel or titanium.
They are inherently more heat resistant.
Routine inspection and cleaning to remove built-up oil, grease, and other flammable substances. This prevents local fueling of fires.
Proper clearance between valves and any ignition sources according to applicable fire codes and standards.
Fireproofing structural supports around butterfly valves to prevent collapse onto valves during a fire event.
Installation of secondary shut-off valves that automatically close or shut off flow in the event of a fire. Provides backup protection.
Strategic placement of valves away from areas most likely to be directly impacted by a fire to minimize risk when possible.
