Abstract
An excess flow and thermal valve assembly includes a valve housing, a valve carried in the housing and displaceable during excess flow conditions to reduce flow of fluid through the assembly, and an intumescent or intumescent material carried in the valve housing and expandable during excess temperature conditions to reduce flow of fluid through the assembly.
Claims20
An excess flow and thermal valve assembly, comprising:
- a valve housing;
- a valve seat carried in the valve housing and having a valve seal surface;
- a valve carried in the housing and movable against the valve seal surface of the valve seat to reduce flow of fluid through the assembly;
- and
- an intumescent carried in the housing on a side of the valve seat axially opposite that of the valve seal surface,
- wherein during excess flow conditions, the valve is displaceable against the valve seal surface of the valve seat to reduce flow of fluid through the assembly, and during excess temperature conditions, the intumescent is expandable to reduce flow of fluid through the assembly.

The assembly of claim 8, wherein the baffle is a rigid ring.
An excess flow and thermal valve assembly, comprising:
- a valve housing;
- a valve seat carried in the valve housing, having a valve seal surface, and being at least partially composed of intumescent material;
- and
- a valve carried in the housing and movable against the valve seal surface of the valve seat to reduce flow of fluid through the assembly,
- wherein during excess flow conditions, the valve is displaceable against the valve seal surface of the valve seat to reduce flow of fluid through the assembly, and during excess temperature conditions, the intumescent material of the valve seat is expandable to reduce flow of fluid through the assembly.
2 more elements
An excess flow and thermal valve assembly, comprising:
- a valve housing;
- a retainer carried in the valve housing, and including a radially outer periphery, an upstream side, a downstream side, a magnet retainer on the upstream side, and a valve retainer on the downstream side;
- a magnet retained by the magnet retainer;
- a valve retained by the valve retainer, wherein during excess flow conditions, the valve is displaceable against a corresponding surface of the valve housing to reduce flow of fluid through the assembly;
- and
- an intumescent disposed in the valve housing, wherein during excess temperature conditions, the intumescent is expandable to reduce flow of fluid through the assembly.
