Sanflo Butterfly Valve — Grooved (SFL-BV-300-G)
Sanflo Butterfly Valve — Grooved, Gear Operated with Tamper Switch (SFL-BV-300-G)
Sanflo butterfly valves are designed for fire protection services, for use in commercial grooved end piping systems. Butterfly valves are indicating valves designed to isolate or regulate the flow of water, and come with a weatherproof supervisory actuator approved for both indoor and outdoor use.
System Design
Sanflo butterfly valves feature a slow-close gear operator that effectively minimizes harmful water hammer, with minimum flow restriction and pressure loss when fully open. The valve connects to the piping system with approved couplings or flange adapters — flow is possible from either direction and the valve may be positioned in any orientation.
