ABSTRACT

The present invention discloses a gate valve with an upper side and lower side
relative the throughbore whereby the lower side is defined by a non-circular
outer body. A circular body cavity is on the upper side and a rectangular body
cavity is the lower side and a portion of the first side whereby the gate is
operable to move up and down within the body cavities. A skirt assembly having
spacers is used which is inserted over the gate to cover the gate opening when
the gate is moved to the closed position to limit debris and other
contaminants from entering the body cavity. The valve may be used with manual,
hydraulic, failsafe operators that are interchangeably mountable to the same
gate valve without otherwise changing the gate valve.
