<p>A magnetically operated excess flow check valve which permits fluid flow through a line when the flow is below a predetermined flow rate but shuts the flow if the flow rate rises above the predetermined limit to prevent uncontrolled flow or discharge of fluids such as might occur if a fluid line is ruptured including unique packaging or mounting of the excess flow check valve in a capsule to facilitate its installation in various flow lines, fittings, pipe systems, appliances and the like. The packaging is in the form of a self contained capsule which can be inserted in various flow passageways with the capsule facilitating assembly of the individual components into a self contained compact package.</p> |
