Diaphragm Valve MV 309 Pressure/temperature diagram Pressure loss curve (standard values for H2O, 2o°C) Q = flow pressure loss and kv value The diagram shows the pressure loss AP in relation to the flow Q. Conversion aid: cv = ky x 0.07; fv = ky x 0.0585 Units: ky [l/min]; cv [gal/min] US; fv [gal/min] GB Pressure connection Connection acc. NAMUR P = operating pressure T = temperature The pressure/temperature limits are applicable for the stated nominal pressures and a computed operating life factor of 25 years. These are standard values for harmless media (DIN 2403), to which the valve...
