Fisher Control Valve
Fisher EZ-OVT Valve Trim
Fisher EZ-OVT valve trim is dual seat valve trim, designed to maintain long term tight shutoff in on/off services that contain particulates in the flow stream, such as catalyst fines. Fisher EZ-OVT valve are used to control and purge the hydrogen and nitrogen transfer gases used in the UOP continuous catalytic regeneration (CCR) refining process.
- A double deadband area is built into the trim to inhibit erosive flow across the seating surfaces as the trim starts to open.
- A special flow deflector directs the flow stream away from the seating surfaces once the valve has traveled off the seat.
