Publication number: 20240036592Abstract: A pressure reducing valve includes a valve housing, plunger, pressure sensing cavity, and biasing member. The valve housing includes a valve inlet and valve outlet in selective fluid communication with each other. The plunger is in the valve housing and movable between a closed position and open position. The plunger is positioned downstream from the valve inlet and upstream from the valve outlet. The plunger includes a venturi and a channel. The venturi is within the plunger and has a venturi inlet and venturi outlet. The channel is within the plunger and is in fluid communication with the venturi. The pressure sensing cavity is in fluid communication with the channel. The biasing member exerts a biasing force on the plunger toward the open position. The channel is in fluid communication with the pressure sensing cavity to provide a fluid pressure that is lower than the outlet pressure during flow.Type: ApplicationFiled: September 8, 2023Publication date: February 1, 2024Inventors: Matthew Guise, William M. Orr, Christopher Corral

Patent number: 7784483Abstract: A backflow preventer that generally includes a modular fluid arrangement having a modular strut, a one-piece modular cage, a relief valve fluidly connected to the modular cage, and at least one in-line check valve removably housed in the modular cage. In operation, when backflow occurs, pressure in a chamber of the relief valve increases to provide a passageway for fluid to flow out of the modular cage, through the relief valve, to the environment. When the backflow stops, the pressure in the chamber decreases and the passageway closes, moving the fluid through the interior of the modular cage.Type: GrantFiled: January 19, 2006Date of Patent: August 31, 2010Assignee: Zurn Industries, LLCInventors: Jonathan L. Grable, William M. Orr

Patent number: 6581626Abstract: A backflow prevention apparatus has a housing with an opening having a predetermined length. A first valve body, and a second valve body may be slidably sealed with one another, and compressed such that their combined length is less then the length of the opening. In the compressed state the valve bodies may be inserted within the opening of the housing and then elongated such that the ends of valve bodies engage and sliding seal with segments of the housing. A spacer may be placed between the first valve body and the second valve body to secure them within the opening. An intermediate valve body may be introduced between the first valve body and the second valve body.Type: GrantFiled: June 28, 2001Date of Patent: June 24, 2003Assignee: Zurn Industries, Inc.Inventors: Brad L.
