Butterfly Gate Key Specifications

Actuation

Pneumatic quarter-turn actuator with solenoid valve for DCS-integrated automated cycling; electric actuator for modulating duct damper applications.

Sealing Type

Resilient elastomeric seat for standard coal and ash conveying; low-leakage metal seat for flue gas duct applications with elevated temperature exposure.

Seating Configuration

Soft seated for ambient-temperature pneumatic conveying of coal and fly ash; metal-seated for flue gas duct isolation at temperatures up to 250°C.

Port Shape

Circular port in wafer or lug body style for pipeline flange mounting; custom rectangular bodies available for duct damper applications.

Body Material

Cast iron or mild steel body for standard service; stainless steel body and disc for corrosive flue gas or wet ash conveying applications.

Size Range

Available from 100 mm to 600 mm for coal and ash pneumatic conveying lines, sampling systems, and auxiliary duct isolation in power plants.

Industrial Applications

Fly Ash Pneumatic Conveying
Installed in fly ash pneumatic transport lines between ESP/bag filter hoppers and ash silos for rapid on/off isolation during sequential hopper evacuation.
Coal Dust Transport Line
Mounted in pulverized coal transport pipes between coal mills and burner fronts for quick isolation during mill trip or burner changeover operations.
Flue Gas Duct Isolation
Used as isolation dampers in flue gas ducts for maintenance access to duct sections, with metal-seated disc for tight shutoff at elevated flue gas temperatures.
