ABSTRACT:
A fluid control device comprises a valve body, a valve plug, a valve cage, and a sealing ring. At least a portion of the sealing ring is disposed within a gap between the valve plug and the valve cage to provide a seal therebetween when the valve plug is in the closed position. The sealing ring includes an L-shaped cross-section that provides an effective seal regardless of the port diameter of the fluid control device, and thus, reduces the number of types of seals required to be stored in inventory for various applications.
