Purpose-built fire sprinkler control

This Milwaukee Valve BB-SCS02 is a butterfly disc valve designed for fire sprinkler systems. It serves commercial and residential installations that require a reliable shut-off point. The gear operated handwheel allows precise manual control during testing or emergency isolation.

Critical pressure and temperature limits

The valve handles a maximum water pressure of 175 psi and operates across a temperature range of -30 to 250 degrees F. These two figures determine whether the device matches the system design; exceeding either limit voids compliance.

Straightforward installation with gear operator

The 1 1/4 in pipe size fits standard sprinkler piping without special adapters. The gear operated handwheel reduces the torque needed to open or close the disc, minimising installer fatigue. The most common issue is debris preventing a full seal, so flush the line before final tightening.
