Water Valve Flow Direction

The flow pattern through a globe valve involves changes in direction resulting in greater resistance to flow causing high pressure drop.

Water valve flow direction.

A valve is a device or natural object that regulates directs or controls the flow of a fluid gases liquids fluidized solids or slurries by opening closing or partially obstructing various passageways valves are technically fittings but are usually discussed as a separate category in an open valve fluid flows in a direction from higher pressure to lower pressure. A check valve is a specialty valve used to keep water flowing in one direction only and prevent flow in the opposite direction. It s important to orient the valve in the right direction with the arrow cast into the side of the valve aligned with flow direction. A back flow preventer of the type often found on outdoor faucets hose bibbs and on lawn sprinkler systems is one example of a check valve.

Check valves tend to be small simple and inexpensive and are often used for backflow prevention in pumps safety applications and such. If the valve is put in backward the flow will force the gasket away from the top of the valve. The globe valve is an excellent valve to use for on off service but is highly suited for frequent cycling and control of fluids anywhere in amount or volume between the open and closed positions. That way water flows against the bottom of the rubber gasket.

Check valves also called non return or one way valves are designed to allow flow in only one direction and to automatically prevent or check back flow if the fluid in the line reverses direction.
