ABSTRACT:
A pressure relief by-pass control valve in a system flowing fluid of changing temperature. The vale incorporates a signalling mechanism to indicate when differential pressures have put the valve in a by-passing mode, including an indicator button displaceable by a valve member in moving toward an open position. Temperature responsive structure closes and opens a gap in the connection between the valve member and the indicator button. As used with a heat exchanger, the valve signals the fact of a clogged heat exchanger core, while obviating giving of a false signal when high pressure differentials resulting from low temperature operating conditions occur.
