A pressure equalization valve enabling equalization of pressure between the between-pane space of an insulating glass unit and ambient pressure, and glass units containing such a valve. The pressure equalization valve generally includes a valve body having a cavity therein and opposed, open ends and an elongated valve plug received in said valve body and securably shiftable along its length between plugged and unplugged configurations. The valve may be secured about an aperture in a glass pane. The valve body has a shoulder at one end, and the pane thick...

The pressure equalization valve generally includes a valve body having a cavity therein and opposed, open ends and an elongated valve plug received in said valve body and securably shiftable along its length between plugged and unplugged configurations. The valve may be secured about an aperture in a glass pane. The valve body has a shoulder at one end, and the pane thickness is sandwiched between the shoulder and a washer preferably press-fitted to the other end of the body. The valve body cavity and the valve plug may include engaging threaded portions enabling the valve plug by rotation thereof to be shifted axially of the valve body between plugged and unplugged positions, the valve body and valve plug having engagable portions securing the plug against accidental escape from the body by axial, non-rotating movement of the plug.
