This valve doesn't need flange becausea tube card hoop is enough.Moreover its spherical surface belt with goodprecision ensures along-term use without leakage.It is also suitable for a single standard card hoop installation.The Grooved butterfly valve presents an optimized structure designwith small volume,light weight and easy accessibility.
Grooved End Butterfly Valves are specifically designed for fire protection systems where it is necessary to visually indicate whether the valve is open or closed. These valves are typically used as system control valves, sectional valves, and pump control valves. They feature a grooved inlet and outlet that are compatible with grooved end pipe couplings, which are UL-listed and FM-approved for use in fire protection systems. The visual indication of valve position helps ensure quick and easy confirmation of valve status, enhancing operational safety and efficiency in fire protection applications.
