Independent Upstream Shutoff

The Master Flo trim is designed to provide exceptional control and shutoff throughout its life by minimizing erosion to the tapered seat faces, which are positioned upstream from the throttling components. This keeps the seats out of high velocity zones that cause excessive erosion. Further protection is provided by a “dead band” between the stationary seat and the nozzle ports, which ensures that flow is minimal during seating.

Per FCI 70-2 – 1998, Master Flo trims achieve Class V shutoff. With suitable actuation, they can provide Class VI shutoff.
