P&ID symbols for valves Commonly used valve P&ID symbols (Piping and Instrumentation Diagram symbols) for manual valves Note that they may differ slightly from one project to another Valve Type Valve P&ID Symbols Application Gate Valve Used when a straight flow of fluid and minimum restriction is desired. Vacuum breaker and air valves are useful tools in the industry for protecting pipelines against vacuum or near vacuum conditions High points in the pipe can be susceptible to these lowpressure conditions during surge events, as pressure waves moving through the system cause a sudden pressure upsurge or downsurge.

It's not always added to a relief valve schematic symbol, since many relief valves are cartridge valves and do not have a separate manifold Poppet This arrow represents the relief valve poppet , which allows the valve to crack open when the pressure on the inlet port gets high enough.
