Commonly used P&ID symbols (Piping and Instrumentation Diagram symbols) for manual valves.
A limit stop in piping refers to a mechanical device or feature designed to restrict the movement of a valve or component within a piping system. It ensures that the valve operates within defined limits, preventing over-travel that could lead to damage or failure. Limit stops are often used in automated systems to enhance safety and reliability by maintaining proper flow control and preventing leaks.
A zone valve is actuated by a thermostat and will allow water to pass from the boiler to radiant floor piping or base board radiators or in some cases a hot water storage tank.
A check valve is designed to stop backflow in a piping system. It allows fluid to flow in only one direction and automatically closes when the flow reverses, preventing any backflow. Check valves are commonly used in various applications, including water supply systems and wastewater management, to maintain system integrity and prevent contamination.
Concentric swage is used for small bore piping while concentric reducer is used for large bore piping. Zach
npt, national pipe thread, is a standard for threads on a screw. I (not a plumber) don't believe "npt valve" makes sense , but probably refers to a valve which has npt threading. Yes, a NPT Valve would be a valve with pipe threads as opposed to a sweat valve which has solder connections. There are several other type of piping connections too.

Mercury is not used in piping.
A check valve restricts the flow of a liquid or gas in a piping system to one direction.
You need symbols on PFDs and PIDs because an exact drawing is more complex than necessary on those documents. Too much space would be occupied by the detailed sketch of something as simple as a valve, when all that those two documents need to show is what kind of valve, how large it is, and where in the process it needs to go.

The term "DN50 valve" refers to a valve with a nominal diameter of 50 millimeters. "DN" stands for "Diameter Nominal," which is a standard measurement used in piping systems to indicate the size of the valve or pipe. DN50 valves are commonly used in various applications, including water and gas systems, to control the flow of fluids. The specifications may vary depending on the valve type and manufacturer.

p&ids r docs used to desribe symbols,abbreivations prefixes and specialised equipments while pfds r sketches that use symbols to represent instruments/vessels used in process engrn and also shows the direction of flow.
NB stands for "Nominal Bore" and refers to the nominal size of the valve in a piping system, typically measured in inches. It represents the internal diameter of the valve or pipe. It is an important parameter used to select the right valve for a specific application.
The star tip is used for a number of things. For example, it's used for piping decorative borders around cakes, for piping flowers on cakes, for piping the egg filling into the cooked egg whites for deviled eggs, and can be used for piping whipping cream on the top of desserts.
Unsure of your question. Firearms are not generally used in piping. Please rephrase your question and repost. Sorry.
