These valves are an excellent option when the material to be handled is abrasive.

They are used in conveying lines that require stops and restarts of the flow. Although the valve is only used in either open or closed position (i.e. not for flow control purposes) the particulate material must be able to pass through when the valve is open.

These valves provide a perfectly smooth passage for the flow of material through the valve, when in open position.
