Abstract
A packing system for a gate valve is disclosed which includes a sealing member structured to be positioned between a compression member and packing material housed in a cavity formed in the upper edge of a valve housing to provide even and consistent pressure of the packing material against the gate of the valve, thereby preventing leakage from about the gate of the valve. The packing may also include a gasket between the compression member and sealing member to provide additional sealing assurance.
