Not sure which type fits?
Selection driven by duty, not by habit
Isolation duty decides the design: a flue gas line that must seal tight needs a double-louver damper with sealing air, a pulverized coal line needs a slide gate with a cavity valve plate, and a gas main that must be absolutely shut needs a blind flange valve. Send us the medium, temperature and leakage requirement and we will tell you which one to specify.
- Flue gas & air ducts — louver dampers, baffle doors and slide gates up to 450 °C continuous.
- Pulverized coal lines — zero-leakage slide gates and coal mill isolation doors.
- Absolute shut-off — blind flange (spectacle) valves and quick-opening chimney doors.
