Flow Characteristics of Super Flow Orifice Valve Chart   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.
