Hello there,
i have been given the task of fitting a 4" pressure control valve into a hydraulic oil pipe. The valve needs to shut off if there is a pressure drop down stream, caused by a burst, to prevent flooding.
Are there any valves on the market that do this or will i have to put a pressure gauge farther down the pipe to link to the valve and send a signal?
