Abstract
In butterfly control valve, a multi-hole orifice is attached downstream of valve to stabilize flow fluctuation. The computational simulation is conducted to analyze valve flow characteristics. The results show that the velocity distribution of downstream of valve with the orifice is improved compared to non-orifice case. Test result in site is 60% reduction in vibration.
