Flow Characteristics of Super Flow Orifice Valve |
|
 |
|
Successfully developed after conducting extensive in house research, the Super Flow Orifice Valve is a one step ahead of Conventional Orifice Valve available in the market. It's performance is dynamically tested by Institute of Oil & Gas Production Technology, ONGCL, Panvel, Mumbai, India.
Flow Performance Curve of NOM - 14R Orifice Valve (Port - 12/64") against different Upstream Pressures i.e.
30 Kg/cm2 & 35 Kg/cm2 are depicted below and comparison with Conventional Square Edge Orifice Valve are also
shown at left.
ANALYSIS OF RESULTS
1) The Critical Flow rate was achieved at
approx 0.878-0.879 pressure ratio of Down
Stream Pressure to Upstream Pressure i.e.
at a pressure differential of 12% compared to
almost 50% in case of a Standard Orifice in
Conventional Orifice Valve.
2) The Actual Critical Flow rates obtained
through the testing were approximately 20%
higher than the calculated theoretical flow
rates. |
