  • Abstract:
  • Control valves are playing a vital role in modern manufacturing process industries around the world. Properly selected control valve increases the efficiency, safety, profitability and ecology. The most common final control element in the process control industries is the control valve. Control valve coefficient describes the relation between flow passage and pressure drop across valve (Flow Capacity). Control valve flow test rig was designed in order to calculate practically the flow coefficient (KV) by standards ANSI/ISA-75.02-1996 and ANSI/ISA-75.01-2002. This flow test rig used to verify the designed KV. It was necessary to t the KV equation for incompressible fluids to proceed with flow sensor selection. It is also described the electronic instrumentation for measuring flow, temperature and pressure difference. This work describes the operation of flow test rig, to determine KV of control valves with incompressible fluid under the regulations established by standards. The results obtained are much encouraging and the accuracy of control valve coefficient is ±1%.
