F16K 11/07

US Classification:

13762533, 13762539, 277647

Abstract:

A control valve having a shiftable valve plug includes a valve body having an inlet, an outlet, a flow passage extending between the inlet and the outlet, and defining a longitudinal axis, a generally cylindrical valve cage disposed within the valve body and sized to receive the valve plug, with the valve cage including at least one aperture comprising at least a portion of the flow passage, a portion of the valve cage disposed adjacent a portion of the valve body at an interface. A seal having a C-shaped cross section is provided and is disposed at the interface between the valve cage and the valve body, and a retainer is disposed adjacent the interface and positioned to secure the seal against movement along the longitudinal axis.

Filed:

Mar 25, 1985

Appl. No.:

6/715630

Inventors:

Kevin G. Schoonover - Atlanta GA
Donald S. Sanders - Norcross GA

Assignee:

Steam Systems and Services Incorporated - Atlanta GA

International Classification:

F16K 4900
F16K 11044
F16K 106

US Classification:

13762548

Abstract:

A valve for controlling or diverting the flow of relatively viscous flowable materials such as polymers or the like. The valve includes a valve plug mounted for longitudinal movement within a valve chamber which receives the flowable material. A pair of antechambers flank the valve chamber, and a pair of portals connect the valve chamber with each antechamber. The valve plug selectably blocks one or the other of these portals, depending on the longitudinal position of the valve plug. A wall of each antechamber is angled to divert incoming flowable material toward the outflow passages individually leading away from the antechambers.
