Here are some key advantages of using
fire protection check valves:
Prevent backflow
Their primary function is to allow water to flow in one direction towards the sprinkler and block any backwards flow. This prevents drainage from sprinkler pipes.
Maintain system pressure
By preventing reverse flow, check valves help the fire pump and air pressure tanks maintain water pressure throughout the piping network.
Isolate sections for repairs
Individual zones or floors can be isolated by closing block valves when repairs are required without draining the whole system.
Fast response
Swing-style clapper checks open extremely quickly to allow water through when a sprinkler head activates.
Reliability
Simple designs with few moving parts mean check valves are highly durable and reliable even after years of infrequent use.
Code compliance
Fire codes usually require check valves to be installed on sprinkler systems to meet NFPA standards.
Built-in strainers
Many fire protection check valve models have integral strainers that filter out particles which could clog sprinkler heads.
Tamper resistance
Valves can be supervised electronically or sealed to prevent unauthorized personnel from interfering with the system.
Using specialized fire protection check valves helps sprinkler systems deliver maximum protection effectiveness as required by building regulations.
