The valve fully opens when the flow rate … WebFrom the above diagram we can conclude that: 1. As flow increases across the control valve, the upstream pressure P1 gets reduced. And downstream pressure P2 gets raised. 2. As flow increases ΔP pressure drop across the valve decreases. 3. At zero or no flow, the ΔP is maximum and the downstream pressure P2 = 0. 4. can you have mild autism
