Dual seat design—EZ-OVT trim features a dual seat design that includes a primary soft seat and a secondary metal seat. This dual seat design provides for long term ANSI and IEC Class VI shutoff.
Off-the-seat deadband—A double deadband area is built into the trim to inhibit erosive flow across the seating surfaces as the trim starts to open.
Flow deflector—A special flow deflector directs the flow stream away from the seating surfaces once the valve has traveled off the seat.
Simple design—The trim has no moving parts (other than standard sliding-stem plug action) that can become inoperative due to the buildup of flow stream particulate such as catalyst fines.
