Check valve

Stop valves are valves - especially hydraulic valves - that can shut off a volume flow of a gas or a liquid. The pressure losses increase with the square of the speed of the flowing fluid .

The shut-off valves include:

• Shut-off valves
• Check valves / one-way flow control valves
• Quick exhaust valves
• Shuttle valves ( logical link "OR" or "OR")
• Two-pressure valves ( logical link "AND" or "AND")

They can also be found as part of the combination of an organ , see Combination (organ) # shut-off valves .
