Control Valves and Cavitation Engineering ToolBox

According the Bernoulli equation when a fluid pass a valve seat and the fluid velocity increase the fluid pressure decrease.. Cavitation. If the speed through the valve is increases enough, the pressure in the fluid drops to a level where the fluid may start to boil, bubble or flash. And when the pressure recovers sufficiently the bubbles will collapse upon themselves.

Poppet valve Wikipedia

A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapour flow into an engine.. It consists of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem. The portion of the hole where the plug meets with it is called the "seat" or "valve seat".

Operation and Maintenance of different valve types

• The valve lifetime in some difficult applications of the hydrocarbon processing industry (HPI) polypropylene or polyethylene production for example – is usually 4000 to 8000 hrs. Poppet valves have an advantage over plate valves because there is less accumulation of the powder like substances that are usually to be found in the gas.

Pressure Balance vs. Thermostatic Shower Valves

Always keep in mind that a pressurebalance valve doesn't pay attention to temperature, so with the valve set at maximum temperature, and the handle turned all the way to "hot", the water coming out of the shower will be as hot as the water heater has to offer (which could be even higher than the setting on the thermostat). Thermostatic Valves

Jan 02, 2008· A Pressure Reducing Valve is used to obtain a desired downstream pressure. The valve is adjusted with that goal in mind. The fact that a valve is adjustable does not necessarily make it a PRV. A balancing valve might be used to balance the flow in a circuit to a desired flow rate. They are not only used in bypass situations.
