A block forged swing check valve body includes a fully encapsulated seat ring. The swing check valve body includes a through hole and a chamber having a shelf portion defined by a D-shaped passageway. The shelf portion overlies an annular shoulder that encapsulates the valve seat. Methods for the manufacturing and use thereof are also provided.

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.

This invention relates to a solenoid housing and to a method for providing a solenoid housing having the base, wall, center pole, and flange integrally connected as a single piece. The instant invention provides for mounting protrusions and window for electrical leads as an integral part of the housing and manufacturing process.
