ABSTRACT:
An orifice fitting has a slide valve seal strip of increased sealing area. The orifice fitting has a body with an upper chamber and a lower chamber, separated by a slot. A plate carrier will move an orifice plate from the upper chamber, through the lower chamber, and down into a flow passage below the lower chamber. A slide valve carrier will open and close the slot between the upper and lower chambers. A seal strip locates on the slide valve carrier for sealing against the seat of the slot. The seal strip has on opposite sides a pair of outward extending flanges. Each flange overlies and contacts a shoulder formed on the upper side of the slide valve carrier. The seal strip has a lower section that locates within the shoulders.
