• Self-operating – no actuator required
• No heat tracers required on tailings lines
• Close coupling the valve to the slurry pipeline allows latent heat in the slurry to prevent freezing
• Unobtrusive – mounts on the top of the slurry pipeline
• Works even under pipeline priming conditions
• Available in 100 mm (4-in) size only, which is suitable for pipelines up to 750 mm (30-in) in diameter
• Multiple connection types available, including flange, Victaulic™, slip-on flange
• Pressure rating available: 150 PSIG, 300 PSIG, 450 PSIG, 600 PSIG
• Multiple drilling patterns available to meet your specifications
• Fully lined, with multiple elastomer options to suit your specific application, including pure gum rubber, chlorobutyl, neoprene, and EPDM

With the pipeline in operation, the advancing slurry column increases the positive pressure in the pipeline and raises the ball to its seating position, effectively sealing the valve.

 
Should a pump or power failure cause the slurry pipeline to go down, so it is not in operation, the ball will drop to the bottom of the valve housing, allowing air to enter around it and rush into the pipeline, effectively breaking the vacuum.

 
Our valve requires no heat tracers for tailings lines. By close coupling the valve to the slurry pipeline, the latent heat in the slurry will prevent freezing. The ball floats in water, so it works even when priming the line.
