Abstract
The present invention provides a method for replacing seals in recreational vehicles gate valves without removing valve housing from plumbing. The method for replacing blade seals in a gate valve features coupling a valve housing of the gate valve to suitable plumbing, the valve housing having a removable blade seal cartridge slidably arranged and latched therein in order to receive a movable blade of a drive unit of the valve gate to control the flow of the medium through the valve gate and to prevent the medium from entering the drive unit; and unlatching the removable blade seal cartridge from the valve housing so as to enable replacement of the blade seal cartridge without having to remove the valve housing from the suitable plumbing.
