Speed Control Assembly Model A-1 Galvanized for Valves

The Viking Speed Control Assembly Model A-1 is engineered to regulate the opening and closing speeds of Viking Deluge and Flow Control Valves in commercial and industrial fire protection systems. Installed within the valve trim assembly, this component controls operational speed to mitigate damaging water hammer effects, prevent pressure surges, and reduce mechanical wear on critical infrastructure. By smoothing valve activation, it protects system piping and components from hydraulic shock during operation.

This assembly satisfies the design and operational requirements governed by NFPA 13 for the installation of sprinkler systems and NFPA 25 for the inspection, testing, and maintenance of water-based fire protection systems. Compliance with these standards ensures that valve response times and pressure regulation mechanisms perform reliably to maintain system integrity and prevent costly downtime.
