A system and method for purging an isolation valve using a liquid purge medium.

Systems and methods for purging an isolation valve with a liquid purge medium

A low-volume non-rising stem gate valve comprising a hollow stem, planetary roller screw and anti-rotation rods. The anti-rotation rods isolate the torque force and maintain the alignment of the planetary roller screw with the stem and the screw shaft, thus reducing the amount of material necessary to support ordinary operational forces.

Systems and methods for torque isolation valve actuator

A coupler that separates a unitary valve stem into two separate but coupled sections to isolates the thrust load from the torque load.

Systems and methods for improved valve stem coupling assembly for isolating the torque load from the thrust load

A seat plate which maintains constant contact and load against the gate to keep sealing surfaces protected is disclosed. The seat plate has a dynamic seat function ie live-loaded to follow the gate surface during stroking and high temperature changes. The valve maintains a positive barrier between body steam chamber and process fluid through port. The valve uses an extended seat plates to maintain constant contact with gate in all positions such that all process is captured and not allowed to enter body chamber. The seat plate allows for sufficient axial seat travel upstream and downstream to balance sealing load on both sides of gate. In addition, an axial hard stop on each seat allowing upstream seat to maintain sealing contact with gate.

A retractable center feed injection device can be employed to feed residual oil into a coke drum as part of a delayed coking process. The retractable center feed injection device can include a housing within which the injection nozzle slides between an extended and a retracted position. A feed inlet is positioned on an opposite side of the coke drum from the retractable center feed injection device. When in the extended position, the injection nozzle can couple with the feed inlet and thereby form an extension of the feed inlet into the center of the coke drum. In this way, the residual oil never flows through the housing.

Retractable center feed injection device

A center feed system allows residual byproduct to be injected into a vessel from within the center of the vessel. The center feed system can include an inlet sleeve that is attached to the vessel and a retractable injection nozzle that extends into the vessel to inject residual byproduct into the vessel and that retracts into the inlet sleeve after injecting the residual byproduct. A retractable injection nozzle may include one or more openings that each includes an insert that can be removed from the opening. The inserts can therefore be replaced to customize the functionality of the nozzle or to replace the inserts when they have become worn.
