The following process flow diagram shows some instrumentation around a compressor system, namely Pressure indicator $$(\mathrm{PI})$$, pressure controller $$(\mathrm{PC})$$ and safety relieve valve. Perform a HAZOP around the node: Operation valve, process parameter: Pressure. You will have to identify two deviations (low, high), possible causes and consequences.
