For a steam engine, the steam(throttle) valve that sets the engine speed/power is often known as a regulator.

What is steam turbine governor valve?
In large turbines, a valve controls steam flow to groups of nozzles. The number of open valves controls the number of nozzles in use according to the load. A bar-lift or cam arrangement operated by the governor opens and closes these valves in sequence. Such a device is a multi-port valve. Using nozzles at full steam pressure is more efficient than throttling the steam.
What did people use before the steam engine?
Before the steam engine.... "people power" and "animal power."
What material steam turbine used for?
he use bronze he use wood.
Which valve is the preferred valve to use as flow control valve at the pump discharge 8 inch size ball valve can be used for the same application?
I would use a butterfly valve to set the flow and a pitot tube to measure it. Nexus Valve makes a good one and it is price competetive as well.
What type of starting system in high bypass turbofan engine?
High Bypass turbofan engines use pneumatics (air) for starting the engines.
Why you use throttle valve in steam engines?
Athrottle valve controls the flow of steam to the engine. Without throttling the steam the engine will simply run full speed and vary in speed as the load increases and decreases. The throttle valve maintains a steady speed by opening as the load increases and closing as the load decreases.
What were the steam engines first use?
The first steam engines used for pumping water out of mines.
Do aircraft designers still use steam engines 2014?
Aircraft designers didn't use steam engines in 1903, either.
Why do you leave a petrol car in gear but a diesel car in neutral for additional breaking?
Engine braking is caused by the vaccum of the engine attempting to pull air through the closed throttle valve. Nearly all petrol (or gas for us in the US) engines use a throttle valve. Diesel engines on the other hand do not have a throttle. They are controlled solely by the amount of fuel injected into the cylinders. Not having a throttle valve, there is no restriction to the engine provide a vaccum when deccellerating, and hence, no engine braking. On large trucks (or lorries) the diesel engines will often have installed a valve in the exhaust system to provide the same effect, or they will have a compression release built into the valve train to do the same thing (often referred to as a "Jake Brake" as they were originally manufactured by the Jacobs company).
Do modern airplanes use steam engines?
No and never have
Who would use a steam engine?
Someone who doesn't want to burn gasoline. A steam engine has the ability to use anything that will burn. Had the technology been applied to steam engines like it was to gasoline engines, we possibly would have some viable steam engine transportation today. Steam engines were less efficient than gasoline or diesel engines, that is why they are not used much today.
What engines did the titanic use?
Two triple expansion steam engines and an exhaust turbine
Did they use steam trains in 1948?
Yes, steam engines were still very much in use in 1948, however diesel electric engines were gradually coming to most railroads.
Have steam engines been replaced?
The reciprocating steam engine is no longer in widespread commercial use.
What did people use before the diesel engine?
Steam engines.
Are steam engines still being used?
Steam engines presently produce more power than all other types of engines combined. Most steam engines take the form of the steam turbine engine. The steam turbine is responsible for generating about 86% of the electric power used on this planet. Reciprocating steam engines are still in use for limited applications, but are generally considered obsolete. Steam engines, either the piston or turbine type were used on most big ships until recently, and there are still a few steam locomotives about.
Can a ball valve be used to throttle flow?
no it can't , valves you can use are a prv pressure reducing valve or a globe or flow valve
