Abstract: A valve assembly includes a plug extending along a central axis and including a plug body having an external plug surface. The external plug surface tapers radially outwardly in a first direction along the central axis. The valve assembly further includes a sleeve having an internal sleeve surface defining an interior cavity. The internal sleeve surface tapers radially outwardly in the first direction. The plug body is positioned within the interior cavity of the sleeve. The plug is rotatable about the central axis relative to the sleeve, and the plug is also translatable along the central axis relative to the sleeve.

Abstract: A valve includes a valve body including a housing. The housing has a first internal housing surface defining an internal chamber. The valve further includes a valve assembly including a cartridge and a sleeve fixedly secured to the cartridge. The sleeve has an internal sleeve surface defining an interior cavity. The valve assembly further includes a plug positioned within the interior cavity and including a plug body. The plug body has an external plug surface configured to sealingly engage the internal sleeve surface. The cartridge is removably coupled to the housing such that the sleeve is disposed within the internal chamber of the housing.

Abstract: A modular valve body with a bimetallic option is shown and described herein. The modular valve body generally includes at least one end connector element joined to a housing. The housing may be formed from a first material, such as carbon steel. The end connector element may be formed from a second material, such as monel. In some versions of the modular valve body, in order to join the end connector element and the housing, the end connector element is rotated and pressed against the housing to heat both materials and create a friction weld therebetween.

Abstract: A computer-implemented system for delivering information comprising: a sender device with an email client for composing and sending an original email message to a Simple Mail Transfer Protocol (SMTP) listener server with encryption enabled; a message processor that extracts the message body payload from the email message, stores it in a database, and creates a new email message with a message body containing a reference to the message body of the original email message; a file repository for storage of attachments to the email message; and an SMTP sender that sends the new email message to a recipient mail server. The listener server assigns the message to the message processor, and the new email message contains links to the attachments residing in the file repository. A method utilizing the system described above.
