摘要：A valve assembly () for measuring differential pressures in a fluid system wherethe valve assembly includes a differential pressure sensor () for registration ofdifferential pressures, a first cavity () with a calibrating cone () displaceable between
measuring and a zero point calibration/flushing position. The valve assembly () includes avalve body () with two connections () and a second cavity () arranged with a safety valvecone () which protects the differential pressure sensor (). The safety valve cone (), bydifferential pressures higher than a dimensioned value, is moved in a direction towardsthe low pressure side and, as a result, a passage between high and low pressure side isopened, from one connection () to the other connection () via the second cavity () and viaprovided cavities () and recesses () in the safety valve cone (), whereby a pressureequalizing occurs.
