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.

Abstract: The coupling comprises a flexible conduit, a packoff assembly, and a gland nut for compressing the packoff assembly. The conduit passes through a passage in a first member and is secured to the outlet of a second member. The nut is threaded into the passage of the first member to compress the packoff for sealing securement of the conduit to the first member even though the axes of the passage and of the outlet are not coincident. A collar is disposed on the interior end of the conduit to prevent the conduit from blowing out of the passage if the conduit should break or disconnect from the second member.

Abstract: A gate valve [10] is disclosed having a secondary seal, wherein the gate [15] forms a metal to metal seal with the seat [29, 134] and wherein a resilient seal [36a] is moved toward the gate [15] in a closed position to form a secondary fluid-tight seal with the gate [15]. A device [31, 34] for deenergizing the secondary seal is provided in order to prevent wear of the secondary seal upon opening of the gate and also to reduce the gate [15] drag caused by the energized secondary seal. Also disclosed is a pressure relief mechanism [40, 141] for the secondary seal adapted to prevent damage to the seal and a mechanism for evenly applying opposing secondary seals.

Abstract: A orifice fitting for measuring gas flow in gas pipelines has an energized seal. The orifice fitting has a plate carrier which moves downward into a seat slot to position an orifice plate in the gas flow. An annular seal mounts to the plate carrier for engaging a downstream side of the seat slot. The seal is energized or pressed outwardly by hydraulic fluid pressure. The plate carrier has a chamber containing hydraulic fluid and a piston. A pin protrudes outward. The orifice fitting slide valve carrier engages and pushes the pin downward as the slide valve carrier moves to the closed position.
