A valve assembly having a body forming a bucket having a sidewall extending between an open end and a closed end along a bucket axis. A first conduit and a second conduit extend from the sidewall, wherein the first and the second conduits extend along a conduit axis that is perpendicular to the bucket axis. A frame inserts into the bucket along the bucket axis and includes a valve seat and a valve member biased against the valve seat. A guide is provided in the bucket between the closed end and the frame and extends along a guide axis between a first opening arranged in a first plane and aligned to receive fluid flow from the first conduit and a second opening arranged in a second plane and aligned to direct fluid flow through the valve seat. The first and second planes are not parallel to one another.

Two problems with existing electronically controlled mixing valves for domestic use is their size and difficulty accessing and repairing them. Their size means that they often become hidden behind wall linings, and because of the way in which they are plumbed into the pipework of a house, they are difficult to access and remove for repair or replacement. Disclosed is a compact and replaceable mixing valve cartridge that can be mated to a fixed fitting that is permanently plumbed into the pipework of a house. The compact size allows the cartridge to be positioned behind the type of removable face plates that are often installed over existing manually operated mixing valves. Simplified valve actuators and a compact mixing and temperature sensing configuration have facilitated the compact size. The valve cartridge can simply be accessed, unbolted and removed, without the need for extensive plumbing re-work.

A hydraulic valve includes a valve housing, a valve cone, a spring housing, a check valve, a first hydraulic connection and a second hydraulic connection. The valve housing has a valve seat and the valve cone is movable in the valve housing between a closed position and an open position. In the closed position, the valve cone is in contact with the valve seat and blocks a first flow path between the first and the second hydraulic connection. In the open position, the valve cone is lifted off the valve seat and the first flow path is opened. A spring element is disposed in the spring housing, which biases the valve cone into the closed position. The check valve is disposed in the valve cone and opens a second flow path from the second hydraulic connection to the first hydraulic connection when pressure is applied to the second hydraulic connection.

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.

An electronic bypass (eBypass) cartridge assembly and method for installing such, including a bypass valve defining a first chamber; a valve body defining a second chamber; and a check valve preventing flow from the second chamber to the first chamber. A bypass tube defining a third chamber, and a solenoid assembly, wherein the solenoid assembly controls flow between the first chamber, the second chamber, and the third chamber. The eBypass cartridge assembly may also include a cartridge attachment interface, and a sealing surface defined by the bypass valve, or an LVDT assembly configured to sense a position of bypass valve, or a valve seat formed on a spring housing, wherein the sealing surface is configured to seal to the valve seat in a fully closed position, or a single bypass input tube and a single bypass output tube.

A valve cartridge assembly supported by a receiver and fluidly coupled to a waterway assembly. The waterway assembly includes a base and a plurality of flexible tubular members. A gasket is received intermediate the receiver and the waterway assembly.

A pressure relief valve assembly includes a pressure relief valve having a valve bushing received in a valve bore of a housing bore, and a valve body biased against a valve seat by a spring guided in the valve bushing. The valve body includes first and second control surfaces subjected in an opening direction, respectively, to a pressure to be limited and to a control pressure. A fixing device disposed on the valve bushing axially supports the valve bushing in the housing bore. The valve bushing has a radially protruding sealing collar which sits against a peripheral wall of the housing bore and seals an annular chamber carrying the pressure to be limited against an annular control chamber carrying the control pressure. Both the chamber and the control chamber are radially delimited on one side by the housing bore and on the other side by the valve body.

A valve cartridge assembly supported by a receiver and fluidly coupled to a waterway assembly. The waterway assembly includes a base and a plurality of flexible tubular members. A gasket is received intermediate the receiver and the waterway assembly.

A ball valve includes valve seats surrounding a valve ball and a valve housing surrounding the valve seats. A central flow passage extends through the valve seats, the valve ball, and the valve housing. Seals are positioned between a non-vertical bottom wall of each valve seat and corresponding non-vertical end walls of the valve housing. When a fluid pressure is applied to the ball valve in a closed position, one of the valve seats moves away from the valve housing to disengage the seal from the corresponding non-vertical housing end wall. The valve seat's movement provides an equalizing flow passage between the valve seat and the valve housing and into an interior portion of the valve ball, thereby allowing for pressure equalization that prevents deformation of the valve ball. The valve housing is formed by valve seat carriers, a cavity in a valve sub, or a combination thereof.

An electromagnetic rising stem valve includes a stopper configured to block flow of fluid within a pipe. The stopper is connected to a shaft configured to be rotated via an electromagnetic force generated between magnets attached to the outside of the shaft and magnets surrounding an outside surface of a section of the valve. The rising stem valve is further able to include a second shaft which is directly rotated by the electromagnetic force, to open, closed, and one or more semi-open positions, and which is coupled to the shaft connected to the stopper via gearing. Advantageously, the one or more shafts and any gearing is entirely contained within a gear housing, with the electromagnetic force being generated by interaction with magnets outside the housing entirely, preventing unwanted leakage of fluid from the pipe into the environment.
