In a combined DPV system, what is the maximum number of sprinklers that can be supplied through any one check valve?

In a combined Double Check Valve (DPV) system, the maximum number of sprinklers that can be supplied through any one check valve is 600 sprinklers. This limit is set to ensure that the system adheres to hydraulic performance requirements and maintains adequate water supply pressure throughout the system.

This maximum sprinkler count helps to prevent overloading any single valve, which could lead to insufficient flow rates or pressure issues in the system. It also serves to ensure that the system can operate effectively during fire suppression scenarios, where reliable and consistent water flow is crucial. By capping the number of sprinklers at 600 per check valve, it allows for better maintenance, monitoring, and management of the sprinkler system as well.

Choosing a higher number of sprinklers per check valve could result in significant operational challenges, including potential failure of the system in achieving desired performance during emergencies. Thus, adhering to this specified limit is critical for effective fire safety design and compliance with recognized standards.
