   Flapper valve; Flow divider valve: a valve providing a plurality of output flows from a single fluid source [2] Flutter (Heimlich) valve: a specific one-way valve used on the end of chest drain tubes to treat a pneumothorax; Foot valve: a check valve on the foot of a suction line to prevent backflow

   The "live" zero of 0.2 bar or 3 psi is set by the bias spring which ensures that the device is working in its linear region. The industry standard ranges of either 3-15 psi (USA), or 0.2 - 1.0 bar (metric), is normally used in pneumatic PID controllers, valve positioning servomechanisms and force balance transducers.

   As the tank water level drops, the float descends and actuates the fill valve. Water is fed to the tank to replenish its supply, and a smaller flow is directed into the overflow tube to refill the bowl. Once the flapper valve closes, the water flow from the fill valve continues until the tank level again reaches the fill line.

5. Check valve - Wikipedia

   en.wikipedia.org/wiki/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] Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various ...

   en.wikipedia.org/wiki/Flush_toilet

   In North America, newer toilets have a 3 in (76 mm) flapper-flush valve. Older toilets have a 2 in (51 mm) flapper-flush valve. [7] The larger flapper-flush valve is used on toilets that use less water, such as 1.6 US gal (6.1 L) per flush. Some have a bell inlet for a faster more effective flush.

7. Globe valve - Wikipedia

   en.wikipedia.org/wiki/Globe_valve

   Globe valve. A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. [1] Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle.
