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.
