A valve assembly includes a body, a fitting, and a stopper assembly. The body has a first end and a second end. The body includes a connector portion positioned at the first end, a nozzle portion positioned at the second end, and an intermediate portion connecting the connector portion to the nozzle portion. The connector portion includes a peripheral wall having a crimped end that defines a fluid inlet. The nozzle portion defines a fluid outlet. The connector portion, the intermediate portion, and the nozzle portion cooperatively define a fluid flow path extending from the fluid inlet to the fluid outlet. The fitting is disposed within the peripheral wall. The fitting is held within the peripheral wall by the crimped end. The stopper assembly is coupled to the body along the intermediate portion. The stopper assembly is configured to facilitate selectively restricting a flow along the fluid flow path.

A device and method for dispensing a flowable medium which is an adhesive, a hot glue or a hot melt adhesive. The device has a housing with an interior space and a rod mounted in the housing, wherein the rod is movable by means of an actuator between a first end position and a second end position in an axial direction. The device comprises a diaphragm, wherein the rod passes through the diaphragm, wherein the diaphragm is mounted in a sealed manner in the housing radially on the outside and is mounted in a sealed manner in the rod radially on the inside, wherein the diaphragm divides the interior space into a first cavity and a second cavity and separates the first cavity from the second cavity in a fluid tight manner, and wherein the first cavity serves to hold the flowable medium. The device has at least one channel which opens into the first cavity and through which the flowable medium can flow into the first cavity, and a dispensing opening into the first cavity for dispensing the flowable medium, wherein the rod has a sealing section, and wherein the sealing section closes the dispensing opening in the first end position and is arranged at a distance from the dispensing opening in the second end position. A pressure medium acting on the diaphragm is arranged in the second cavity.

A valve system (1) comprising a valve having a valve stem (50), a valve body (20) and a stuffing box (30) assembled to the valve body, the valve system comprising a washer (60) in contact with the stem (50) and the stuffing box (30), the washer (60) comprising an electrically conductive material.

Provided is a gas valve, particularly configured for use in a water carbonation system or appliance; and further provided is a system or appliance including such a valve.

An electrically operated valve having excellent wear resistance while suppressing cost is provided.

The electrically operated valve comprises a valve main body having a valve seat; a motor including a stator fixed to the valve main body and a rotor driven to rotate with respect to the stator,

a planetary gear type deceleration mechanism configured to decelerate rotation of the rotor to transmit to an output gear, a valve member configured to be movable toward and away from the valve seat in an axial direction, and a feed screw mechanism configured to convert rotational movement of the output gear into movement of the valve member in the axial direction. The planetary gear type deceleration mechanism includes a sun gear coupled to the rotor, a planetary gear engaged with the sun gear, a carrier for rotatably supporting the planetary gear, an annular ring gear engaged with the planetary gear, and a sliding member abutting against an axial end of the sun gear. The output gear has a different number of teeth than the ring gear, and engages with the planetary gear, and the sliding member is made of a different material from the material of the sun gear.
