Tilting-disc inconel check valve Check valve symbol on piping and instrumentation diagrams.The arrow shows the flow direction. Vertical lift check valve. A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.
These types of valves are also known as automatic control valves. The hydraulic actuators respond to changes of pressure or flow and will open/close the valve. Automatic control valves do not require an external power source, meaning that the fluid pressure is enough to open and close them.
Pilot valve: regulates flow or pressure to other valves; Petcock, a small shut-off valve; Pinch valve, "beach ball valve": simple, single-part two-port check valve made from soft plastic and molded onto inflatable units such as beach balls, air mattresses, water wings; can be inflated by pump or by mouth
P&IDs are originally drawn up at the design stage from a combination of process flow sheet data, the mechanical process equipment design, and the instrumentation engineering design. During the design stage, the diagram also provides the basis for the development of system control schemes, allowing for further safety and operational ...
The check valve aspect is a conical valve or 'mitre valve', [i] held against a matching conical seat by a spring. As these valves must work at high pressure, the valve faces are accurately ground to shape. The valve is also held accurately concentric to its seat by a fluted extension, usually cross-shaped or three-winged, below the seat.
Shut-off / On-off valve: These valves are either completely open or closed. Examples: Gate valve, ball valve, globe valve, angle valve, pinch valve, diaphragm valve; Check valve: Allows flow only in a single direction; Steam conditioning valve: Regulates the pressure and temperature of inlet media to required parameters at outlet.
