Fire Protection Grooved Butterfly Valve

Products Details

What is the Fire Protection Grooved Butterfly Valve？

Grooved butterfly valve (Gear actuator & tamper switch) is light weight valve with signal gearbox, and it is grooved connection. The valve is fully open or closed when the disc is rotated a quarter turn.The Grooved signal butterfly valve is a grooved clamp connection valve designed completely based on the principle of symmetry. It is symmetrical in the axial centerline, radially centerline, two-way full pressure seal, with a signal device, which can give the valve action. It is mainly used in various pipelines of water supply and drainage, building fire protection and other systems, especially in fire protection pipelines, to cut off and adjust the flow of the medium.
