What are the Types of Grooved Butterfly Valve?
What is a groove valve?
Designed to minimize water hammer caused by flow reversal, the valve is furnished with grooved ends for installation with GRINNELL Grooved Couplings or Flanged Adapters.
Grooved pipe couplings and fittings are used to join pipes in both wet and dry systems. They provided some flexibility in terms of movement and deflection to the piping system.
Two sealing types for grooved butterfly valves
There’re two sealing types for grooved butterfly valves—metal sealing and elastic sealing.
Valves that use metal sealing usually last longer than valves that use elastic sealing, but they are difficult to be completely sealed. Metal sealing can endure high working temperatures while elastic sealing is limited to changes in temperature. If the butterfly valve is used to regulate flow, it is important to correctly select the size and type of the valve.
The sealing ring of the elastic sealing valve can be embedded in the valve body or attached around the butterfly plate. This sanitary butterfly valve is suitable for use in food, medicine, petrochemical, industrial environmental protection, and high-rise buildings.
