## 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.
