WEBCheck 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. [ 1 ]
What are Check Valves? Types of Check Valves & Their Symbols
WEBA Check valve is a mechanical device used in piping and pipeline systems to prevent back-flow. Check valves allow fluid flow only in the forward direction that’s why it is called a one-way valve or non-return valve. They work on the principle of differential pressure.

WEBCheck valve symbol. Check, or non-return valves only allow flow in one direction. In the symbol shown on the left, the flow is allowed from the bottom pipe to the top pipe, but not back the other way. There is no spring shown as this valve does not have one; instead, it will rely on gravity to keep it closed.

WEBCheck Valve. The simplest DCV (Direction Control Valve ) is a check valve. A check valve allows flow in one direction, but blocks the flow in the opposite direction. It is a two-way valve because it contains two ports. Figure shows the graphical symbol of a check valve along with its no-flow and free-flow directions. Symbol Of Check Valve:
