Auto shut-off valve for hose failure

[billhowcroft]

Does anyone know of a valve for automatically shutting off water pressure in the event of downstream line (hoses, fittings etc) failure. The application is for water for a test rig at up to 6000psi with small diameter hoses (equivalent to half-inch). I have heard of such devices on fire hydrant systems and also on washing machine hoses but not for higher pressure industrial equipment.

These are generally called excess flow valves. They shut when the flow rate exceed a certain value, which usually indicates a failed hose. For your application I would think that restrictive orifices might be sufficient.

Check with Swagelok. Take a look at the XS series excess flow valves.
