Regulator flow capacity Kv value, is the important parameter, it reflects the fluid through the valve ability, namely regulator capacity. According to the regulator flow capacity Kv value calculation, and can determine the diameter. In order to properly choose regulator must be accurate calculated the rated flow coefficient Kv value. Regulator rated flow coefficient is defined as the under prescribed conditions, namely the valve both ends pressure differential is 105Pa, fluid density is 1g/cm3, the flow number with m3 / h or t/h flow through regulator when rated stroke.
