A ball valve system includes a body having an upstream end and a downstream end and a ball within the body between the upstream end and the downstream end, the ball being rotatable about a vertical axis to move between a closed position and an open position. The ball valve assembly includes a stem movable in an actuation direction substantially parallel to the vertical axis, the stem including a recess at a proximal portion of the stem, a guiding member extending within the recess of the stem, the guiding member being configured to prevent rotation of the stem or cause rotation of the stem, and a lubrication port in fluid communication with the recess.

A plug valve assembly has a valve body with an inlet and an outlet each defining a fluid passageway in fluid communication with a cavity defined within the valve body. The valve body further has a collar defining a service opening extending upward from the valve body. A plug with a spindle top and a plug body is disposed within the cavity. The plug has an opening that is operable to obstruct the fluid passageway when it is in a closed position and to connect the inlet to the outlet when it is in an open position. The spindle top of the plug has a hexagonal outer profile and a through opening and adaptable to engage with a variety of actuating devices. A threaded cap is removably engaged with the collar of the valve body and is operable to retain the plug within the valve body cavity.

A system for distributing high viscosity grease to at least one plug valve includes a replaceable cartridge with a body having a chamber and a piston disposed within the chamber. The piston defines a first space within the chamber for receiving solid grease and a second opposing space within the chamber for receiving fluid for driving the piston to compress the solid grease received within the first space. A manifold detachably couples to the replaceable cartridge and has a manifold chamber for receiving grease flowing under compression from an outlet of the cartridge and a plurality of valves in fluid communication with the manifold chamber for selectively distributing grease to corresponding grease ports of the at least one plug valve.

The present disclosure provides a valve enclosure and side handle faucet system comprising the valve enclosure. The valve enclosure comprises an inlet portion, an outlet portion and a valve cavity. The valve enclosure further comprises a ball valve and is mounted to the side of a spout such that fluid enters the valve cavity perpendicularly from a fluid inlet line and exits the cavity perpendicularly from an outlet such that the distance between the input and output flow to the cavity is minimized. The valve enclosure also comprises an interchangeable housing configured to surround the valve enclosure.
