Abstract
The present disclosure provides gas valve assemblies that include a replaceable excess flow valve within a movable flow control body that is removably secured within a valve seat housing. The gas valve assemblies permit the replacement of an excess flow valve without interrupting the supply of gas to a structure and without replacing gas piping.
Claims20
A gas valve assembly comprising:
- a valve seat housing having a wall and a central opening, and including:
- a first hub extending from the wall of the valve seat housing and having an opening extending therethrough;
- a first gas port extending through the wall of the valve seat housing aligned with the first hub opening so that the central opening is in communication with the first hub opening;
- a second hub extending from the wall of the valve seat housing and having an opening extending therethrough;
- a second gas port extending through the wall of the valve seat housing aligned with the second hub opening so that the central opening is in communication with the second hub opening;
- a flow valve body within the central opening of the valve seat housing, the flow valve body having a main flow bore extending therethrough and a bypass bore extending therethrough, wherein the main flow bore is angularly displaced from the bypass flow bore;
- and
- valve holding assembly having a lid releasably secured to the flow valve body and a valve holding body extending from the lid into a valve receptacle within the flow valve body, the valve holding body having an excess flow valve removably positioned within an EFV bore within the valve holding body.

A gas valve assembly comprising:
- a valve seat housing having a wall and a central opening, and including:
- a first hub integrally or monolithically formed into the wall of the valve seat housing and having an opening extending therethrough;
- a first gas port extending through the wall of the valve seat housing aligned with the first hub opening so that the central opening is in communication with the first hub opening;
- a second hub integrally or monolithically formed into the wall of the valve seat housing and having an opening extending therethrough;
- a second gas port extending through the wall of the valve seat housing aligned with the second hub opening so that the central opening is in communication with the second hub opening;
- and
- a flow valve body within the central opening of the valve seat housing, the flow valve body having a main flow bore extending therethrough and a bypass bore extending therethrough, wherein the main flow bore is angularly displaced from the bypass flow bore, the flow valve body having a removable excess flow valve positioned within main flow bore.
