Sodium is a solid at room temperature and becomes a liquid at 97.5 degrees Celsius. Sodium cooled valves are exhaust valves in a cylinder head of an engine that open to release exhaust gasses that were formed due to combustion of fuel and air inside the cylinders and typically get very hot. The sodium cooled valves and exhaust valves filled with sodium inside, the sodium helps the valves be cooler than if they were just solid.

What are igv valves?
Inlet Guide Valves
What are the advantages and disadvantages of an air cooled condensers over that of a fan cooled in refrigeration?
The air cooled can be more efficient because they will use less energy. They are difficult to maintain if it stays too hot.
When are superheater safety valves set to open?
after the main safety valves are open
Does low suction pressure have an effect on reciprocating compressors?
At very low suction pressure, the suction valves of reciprocating compressor will not work and there will be no gas in the cylinder during compression stroke, resulting some damage to the suction valves. If low suction pressure trip protection is not provided there can be some abnormal damage.
For what purpose is a pneumatic valve used?
Pneumatic valves are used to close valves in high-speed internal combustion engines, pneumatic valves are mostly to help racing engines to get to high speeds.
Commercial use of sodium?
Pure sodium? A lot of engines have "sodium cooled valves." They drill out the valve stem and fill it with metallic sodium, which melts at a low temperature. After the sodium melts, it sloshes around in the valve and pulls the heat away from the valve face, making the valve last longer and work better.
Why do intake valves last longer than exhaust valves?
Intake valves are cooled by the gasses passing through them, exhaust valves are heated by the gasses passing through them and can be burned by overheating.
Why sodium thiosulphate solution is prepared in freshly boiled and cooled water?
why sodium thiosulfate to be prepared in hot water only

What are some methods for cooling nuclear reactors both in the UK and abroad?
Most reactors are cooled by water. Some are cooled by liquid metal, like sodium. Some are cooled by gas. Some are cooled by molten salt. There are different reasons for designing and building a reactor that is cooled by each of the methods cited, and additional reading will have to be done by the investigator to discover why. A link is provided to get you started.
Oceanic crust is composed of a volcanic rock that forms from quickly cooled lava called?
mainly basalt
What is ACCU in air conditioning design?
ACCU - Air-Cooled Condensing Units Air-cooled condensing units covers products that are specifically designed to provide cooling to other equipment and systems that incorporate evaporators (and associated expansion valve control systems). Air-cooled condensing units are factory-assembled units that consist of an air-cooled condenser, one or more compressors, and interconnecting pipe work. They may include liquid receivers, filter driers, oil separators, shut off valves and related controls, and a weatherproof housing.
When valves of veins do not function properlythey are referred to as competent valves?
They would be considered incompetent valves because they are not working properly. You need all the vein valves to work properly for maximum functioning.
What is the work of valves?
Valves - allow fluids or gases to only flow in one direction. They're control devices.
