A ball valve assembly includes an outer sleeve having first and second pillars and defining an outer sleeve hollow, a first notch, a second notch, and a third notch, wherein the first pillar of the outer sleeve at least partially defines and is positioned between the first and second notches, and the second pillar of the outer sleeve at least partially defines and is positioned between the second and third notches.

Valve assembly

An isolation valve has a reversible handle and multiple seals between the valve stem and valve housing. The handle includes a portion that engages a handle stop that is attached to the valve body. When the handle is reversed, the stop is moved to another handle stop opening in the valve body. Thus, the handle direction can be reversed without removal of the handle. A locking plate may be used with the isolation valve. The locking plate includes portions that engage a lock and the handle stop. When the handle direction is reversed, the locking plate can be rotated around the stem to engage the repositioned handle stop.

A plumbing fitting that includes: a fitting body having a plurality of ends; and a cover element joined to the body with a weld in proximity to and spaced from an interface in contact with a potable or non-potable aqueous medium. The body and the cover element are fabricated from a lead-free or low lead, copper or copper-silicon alloy having a thermal conductivity of &#x2264;45 W/(m*K). Further, the weld has a centerline that is &#x2264;6.4 mm from the interface and/or a heat affected zone that has an average width &#x2264;400 &#x3bc;m and is spaced from the interface. The plumbing fittings include but are not limited to ball valves, gate valves, elbows, check valves and other fittings without stems.

A valve system includes a spring-biased locking slide plate which extends in an axial direction parallel to and offset from the axis of the valve stem and selectively extends through a base plate mounted to the top of a valve to selectively engage stop tabs on the valve body. The locking slide plate also extends through the valve handle and through a locking member to selectively lock the valve in open or closed positions. In one embodiment, the locking slide plate comprises two sections which include a lower section having tines which selectively engage tabs on the valve body and a second upper section which is spring-biased to the lower section to float to allow the lower section to accommodate different diameter valve bodies.
