The new ORCA® trim provides huge advantages against other solutions. Plates mounted on both sides of the disc with the pressure to drop in several stages and prevent supersonic speed in gases and prevent the cavitation in liquids. One or more sets of plates can be mounted in accordance to the customer needs, allowing an excellent flow control when the valve is partially open. Since the plates are mounted parallel to the disc and moved together with the disc, they do not interfere with the flow when the valve is fully open. This ensures the maximum Kv / Cv value remains as this of a standard valve.
