Patent number: 5088689Abstract: A disk valve construction having relatively movable face to face disk upstream of a sleeve member at an outlet chamber of the valve. The sleeve member includes a truncated conical portion to produce a desired pressure drop, while, at the same time reducing the turbulence of the fluid flow during operation of the valve. The sleeve member is maintained in position by way of pressure of the fluid, thereby avoiding the necessity of epoxy to hold the sleeve member to the valve body. The sleeve can be provided with an end wall with a discharge opening of a predetermined size at the downstream end of the sleeve for producing a predetermined fluid pressure drop.Type: GrantFiled: December 14, 1989Date of Patent: February 18, 1992Assignee: Automatic Control Components, Inc.Inventors: Fred W. Hendricks, Bobby Brooks

Patent number: 5063954Abstract: To reduce the torque required to turn a movable upstream disk relative to an abutting stationary downstream disk in a multiple orifice valve, particularly when the disks are subjected to high fluid pressures, there is provided a removable sleeve or insert at the outlet side of the stationary downstream disk having a support member formed therein for supporting the downstream or outlet side of the downstream disk. The support member may be provided with a central raised portion for supporting the downstream side of the stationary downstream disk along the central axis thereof which is coaxial with the central rotational axis of the movable upstream disk. The supportive sleeve or insert serves to reduce the torque required to turn the upstream disk irrespective of the diameter of the disks. Such a sleeve further reduces the required turning torque in such valve assemblies wherein the abutting faces of the disks are polished to a high level of surface finish quality.Type: GrantFiled: June 18, 1990Date of Patent: November 12, 1991Assignee: Automatic Control ComponentsInventor: Fred W.

Patent number: 5054521Abstract: To improve the turn-down ratio and reduce the erosiveness of the discharge flow in a multiple orifice valve having a movable upstream disk and an abutting stationary downstream disk, particularly when the disks are subjected to high fluid pressures, the disks are provided with cooperating fluid conducting openings having a modified circular sector shape. In the preferred embodiment, the modified circular sector shape of the fluid conducting openings includes a primary opening portion formed in the general shape of a circular sector and a secondary opening portion comprising a pair of substantially semicircular supplemental openings, one of the pair of openings being provided at a radially outermost location along a first one of two radially directed walls defining therebetween the central angle of the circular sector shaped primary opening portion, the other of the pair of supplemental openings being provided at a similar location along the second one of the two radially directed walls.Type: GrantFiled: June 13, 1990Date of Patent: October 8, 1991Assignee: Automatic Control Components, Inc.Inventor: Fred W. Hendrick

Patent number: 5025833Abstract: A disk valve construction having a unitary valve body formed with an internal cavity to receive therein a rotor spool passed through the fluid inlet end of the valve body. A replaceable sleeve member at an outlet chamber of the valve includes a truncated conical portion followed by a cylindrical portion of the fluid discharge end of the sleeve. The sleeve member is maintained in position by way of pressure of the fluid.Type: GrantFiled: October 31, 1988Date of Patent: June 25, 1991Assignee: Automatic Control Components, Inc.Inventor: Fred W. Hendrick

Patent number: 4901977Abstract: A disk valve construction having a unitary valve body. The valve is opened and closed by rotation of a drive shaft which is maintained in geared connection with a rotator spool positioned in an internal cavity of the valve body. The drive shaft extends in a direction substantially perpendicular to the longitudinal axis of the valve body. The drive shaft may be supported in a housing assembly to allow pressurization thereof for valve operation with steam and hazardous materials.Type: GrantFiled: June 2, 1989Date of Patent: February 20, 1990Assignee: Automatic Control Components, Inc.Inventor: Fred W.
