Thermal actuated pressure relief valve

(OP)
I'm am looking for a pressure relief valve that is actuated at a set temperture. ie the device remains closed until it reaches 150F at wich point pressure is released. Does anyone know of such a device?

Thanks

Scott

RE: Thermal actuated pressure relief valve

Search (Thomas register, google, yahoo) for "thermostatic" or "thermostatic relief" valves.

There are a lot of them out there, for instance those provided by pump manufacturers (Cat, Hypro) for thermal relief of positive displacement pumps (eg pressure washers).  Knowing more about your requirements (case pressure, max. differential across valve, flow rate, response time required) would aid in others helping you search.

RE: Thermal actuated pressure relief valve

Most hot water storage tanks have such a valve. These are very common so check with your local plumbing material supplier.

Self-contained temperature control valves work like a pressure regulator using filled capilary temperature sensors.
