SCOPE

DEMCO resilient-seated butterfly valves are an economical alternative to ball, gate or plug valves in many
applications. They are light weight quarter turn devices with few parts. They are designed for bubble-tight sealing
up to rated pressure and are capable of throttling service. They are easily adapted to automatic actuators.
The DEMCO Resilient Seated Butterfly Valve is available in flangeless wafer design or single flange tapped lug
configuration

NAMEPLATE INFORMATION

STORAGE

DEMCO Resilient Seated Butterfly Valves are shipped in the partial open position to
minimize permanent deformation of the resilient seat. The disc edge is contained
within the flange faces of the valve to prevent damage to the sealing area (Figure 4).
Caution: valves with fail open or closed actuators are shipped with the disc in the fail
position and extra care should be given to prevent damage to the disc edges. Valves
should be stored in a clean dry area away from extremes of heat. The resilient seat
surfaces should be protected from sunlight and physical abuse.
