A simplified version of the definition is: The k v factor of a valve indicates "The water flow in m 3 /h, at a pressure drop across the valve of 1 kgf/cm 2 when the valve is completely open. The complete definition also says that the flow medium must have a density of 1000 kg/m 3 and a kinematic viscosity of 10 −6 m 2 /s , e.g. water.
The "CV4000" numbers identify special-quality valves though SQ valves CV numbered before that rule came in retain their original CV number: CV4007 = E91AA – SQ version of 6AL5; CV4010 = E95F – SQ version of 6AK5 or EF95; CV4014 = M8083; The "M8" in the part number denotes that it was developed by the military:
DVT – differential valve tool (for cementing multiple stages) DWOP – drilling well on paper (a theoretical exercise conducted involving the service-provider managers) DWQL – dual-water quicklook log
Specific types of long-term central lines are the Hickman catheters, which require clamps to make sure that the valve is closed, and Groshong catheters, which have a valve that opens as fluid is withdrawn or infused and remains closed when not in use. Hickman lines also have a "cuff" under the skin, to prevent bacterial migration.
Choke valve, Butterfly valve used to limit air intake in internal combustion engine. (Not to be confused with choke valves used in industrial flow control, above.) Clapper valve: a type of check valve used in the Siamese fire appliance to allow only one hose to be connected instead of two (the clapper valve blocks the other side from leaking out)
Honda CVCC engines have normal inlet and exhaust valves, plus a small auxiliary inlet valve. On the intake stroke a large amount of a very lean mixture is drawn into the main combustion chamber; at the same time a very small amount of rich mixture is pulled into the pre-chamber near the spark plug.
