Patent number: 10323759Abstract: Embodiments include a check valve that comprises a valve body defining an inlet port and an outlet port; a disc disposed within the valve body, wherein the disc is coupled to a pivot shaft and the pivot shaft is coupled to the valve body; a lever arm coupled to the disc, wherein when the disc rotates the lever arm rotates; an actuator shaft couple to a motor, and a first interference element coupled to the actuator shaft, wherein the lever arm contacts the first interference element when the disc is in a maximum open position; wherein when the motor rotates the actuator shaft moves longitudinally along its axis to move the first interference element thereby changing the maximum open position. Other embodiments are also included herein.Type: GrantFiled: September 28, 2016Date of Patent: June 18, 2019Assignee: DeZURIK, Inc.Inventors: Douglas J. Tanner, Forrest Halvorson, David G. Hildebrandt, Donald L. Bartell, Jr., Dennis Jay Smith, Jr., Timothy M. O'Shea

Publication number: 20130312837Abstract: An electric motor actuated stop/check valve for industrial use such as liquid pumping systems which has a controlled opening and closing rate when liquid flow is in a forward direction but closes quickly upon reverse flow of liquid with no action from the electric motor actuator. Actuation of the valve is by an electric motor which provides movement to an actuator rod which contacts the disc stem. The disc stem and the actuator rod are not connected which allows the valve disc and disc stem free movement. No action by the electric motor is required. A spring biasing the valve disc toward the closed position and a hydraulically operated valve closing-speed regulator reduces or eliminates slamming of the valve disc against the valve seat. In a preferred method of operation liquid surge pressure transients are reduced or eliminated and slamming of valve components is prevented.Type: ApplicationFiled: May 17, 2013Publication date: November 28, 2013Inventors: Donald L.

Publication number: 20110259433Abstract: An electric motor actuated stop/check valve for industrial use such as liquid pumping systems which has a controlled opening and closing rate when liquid flow is in a forward direction but closes quickly upon reverse flow of liquid with no action from the electric motor actuator. A valve disc having an elongated disc stem contacts a valve seat when in a closed position to stop liquid flow. Actuation of the valve is by an electric motor which provides movement to an actuator rod which contacts the disc stem. The disc stem and the actuator rod are not connected which allows the valve disc and disc stem free movement, by action of the momentarily back-flowing liquid, to a back-flow preventing closed position when liquid forward flow is reversed. No action by the electric motor is required. A spring biasing the valve disc toward the closed position and a hydraulically operated valve closing-speed regulator reduces or eliminates slamming of the valve disc against the valve seat.Type: ApplicationFiled: March 28, 2011Publication date: October 27, 2011Applicant: GA INDUSTRIES, INC.Inventors: Donald L.

Publication number: 20080175726Abstract: A surge anticipator safety check unit for use in a liquid system for preventing damage to a pump and associated components of the system in the event of a loss in pumping pressure is provided. The unit includes a surge anticipator portion having a surge anticipator valve assembly, a hydraulic or electronic controller for operating the surge anticipator valve assembly depending on the conditions in the liquid distribution system, and a sensor associated with the controller for sensing the conditions in the downstream portion of the piping relative to the safety check unit. The surge anticipator safety check unit operates in conjunction with the operation of a check valve member in the piping and an air vacuum portion and operates to eliminate or minimize surge in the system. The valve assembly includes a solenoid plunger connected to a valve member. The plunger is operated by the controller for opening and closing the surge anticipator portion.Type: ApplicationFiled: January 17, 2008Publication date: July 24, 2008Applicant: GA INDUSTRIES INC.Inventor: Donald L.
