BACKFLOW PREVENTION ASSEMBLY HAVING A CARTRIDGE WITH DUAL ZONE TESTING
20230228067 · 2023-07-20 · ·

A backflow prevention assembly includes a body forming two buckets, wherein flow passes through the body from an inlet to an outlet along an axis and consecutively through each of the buckets. A single zone test cover encloses a first of the buckets to form a single zone chamber. A dual zone test cover encloses a second of the buckets with a dual zone cartridge assembly therein. The dual zone test cover has two test cocks. The dual zone cartridge assembly includes a frame having a valve seat, wherein the frame includes a lumen providing fluid communication from a dual zone chamber upstream of the valve seat to a first of the two test cocks of the dual zone test cover, and wherein the second of the two test cocks of the dual zone test cover is in fluid communication with the dual zone chamber downstream of the valve seat.

Backflow prevention assembly with telescoping bias assembly and reversible valve member

A valve assembly with a spring retention assembly including an elongated cylinder portion having an open threaded end and a closed end and an elongated piston portion having a free end and a threaded tab end configured to thread through the open threaded end and, thereby, be slideably captured in the cylinder portion. A spring couples to the body portion and the piston portion to provide a force to urge the body portion and the piston away from one another, wherein the closed end and the free end are similarly shaped so that the spring retention assembly can be reversibly mounted to a valve member that can also be reversibly mounted.

Check valve pivot pin retainer seal

Embodiments relate to a check valve and methods of making a check valve that include a valve body having an inlet end, an outlet end, a flow bore that extends between the inlet and outlet ends, a cavity which intersects the flow bore, and an opening which is connected to the cavity. In certain embodiments, the check valve further includes a cap removably secured in the opening, a seat cartridge disposed in the cavity, wherein the seat cartridge comprises a chamber with a flow bore, a retainer ring positioned in the valve body between the cap and the seat cartridge, a pivot pin retainer seal provided between the retainer ring and the valve body, wherein the pivot pin retainer seal comprises one or more protrusions extending outwardly in a radial direction from the retainer ring to seal on the valve body, and a flapper pivotally connected to the retainer ring, wherein the flapper is pivotable through the chamber between a closed position in which the flapper is positioned against a shoulder in the seat cartridge and an open position in which the flapper is displaced from the shoulder.

CHECK COVER ASSEMBLIES FOR BACKFLOW PREVENTION ASSEMBLIES WITH INTEGRATED TEST COCK PROTECTION SHROUD
20220049786 · 2022-02-17 ·

A check cover assembly for a backflow prevention (BFP) assembly including a dome-shaped base with an upstanding shroud, wherein the shroud forms an inner area configured to receive a test cock to support and protect the test cock. The shroud forms a gap for accessing the test cock to selectively open and close the test cock while installed in the inner area. The base forms a passageway from the inner area into the BFP assembly configured so that when the test cock is open, a pressure reading of a pressure zone in the BFP assembly can be taken via the test cock. A retention fork is in a slit formed in the shroud so that the test cock is captured in the inner area but the test cock can be removed from and inserted into the inner area without rotation when the retention fork is removed from the slit.

A valve assembly includes a valve body defining an internal region, an inlet passageway, and an outlet passageway, wherein the inlet and outlet passageways fluidly communicate with the internal region. A valve seat is positioned within the internal region defining a fluid passageway. A hanger is connected to the valve body. A linkage assembly is pivotally and rotatably to the hanger and a valve member is pivotally connected to the hanger via the linkage assembly, wherein the valve member is movable between an open configuration, in which fluid flow is permitted through the fluid passageway, and a closed configuration, in which the valve member engages the valve seat to at least partially restrict fluid flow through the fluid passageway.
