What is the KVS in the valve parameter?
The Kvs of the valve reflects the passing capacity of the valve
The valve Kvs is to reflect the passing capacity of the valve, which is defined as the pressure at both ends is 1bar, through the flow of the valve, Kvs is a characteristic parameter of the valve, and valve structure, is a constant value.
KVS meaning in valve parameters:Kvs is the coefficient of flow (also called circulation capacity).Kvs refers to both ends of the valve pressure difference of 0.1MPa, water density of 1g/cm^3, when the valve fully open flow. It is an important parameter of the control valve, reflecting the capacity of the control valve.Flow coefficient is a unit of time, in the test conditions, the pipeline to maintain a constant pressure, pipe flow through the valve mass flow, or mass flow. That is, the maximum flow capacity of the valve. The greater the value of the flow system, the smaller the pressure loss when the fluid passes through the valve. The CV value of the valve shall be determined by test and calculation.
