Abstract: A rising stem plug valve has a valve body housing that receives a plug. A handle assembly is attached to the plug for rotational movement of the plug between operative positions. A control assembly is attached to the plug for unseating and seating of the plug within the valve body. The plug includes at least one plug portion having openings corresponding to an interior configuration. Ring cords substantially surround the openings in the plug to create a seal therearound. The plug may include upper and lower plug portions with an untapered portion located between them. An O-ring is located on the untapered portion of the plug to maintain separation between the upper and lower plug portions.

Abstract: A backwash strainer including a body, a strainer element having an inlet side contained in the body, and a space defined between the body and the strainer element. The body includes an inlet to the strainer element and an outlet from the annular space. A nozzle for directing cleaning fluid against the inlet side of the strainer element for dislodging particulate matter from the inlet side of the strainer element mounts to the body. A backwash arm for collecting the cleaning fluid and dislodging particulate matter mounts to the body. The backwash arm is positioned adjacent to and is in close proximity to the inlet side of the strainer element and the nozzle. The backwash arm has an axially extending slot defined by two spaced members having ends positioned adjacent to the nozzle. The backwash arm and the nozzle together may be moveable about a central axis relative to the strainer element.
