A pneumatic system can utilize a pressure relief valve or an emergency stop valve to assist in a safe stop during a power outage. These components help to release trapped air and prevent sudden movement of actuators, ensuring a controlled stop. Additionally, incorporating accumulators can store energy, allowing for a safe and gradual cessation of operation. This ensures the safety of personnel and equipment during unexpected power loss.
Difficult question to answer without context. Key thing to understand is a pneumatic system uses a compressor, whereas a hydraulic system uses a pump. Hydraulic fluid is essentially incompressible, whereas compressed air will fill any volume. Ask yourself: What is my pneumatic/hydraulic system supposed to do? How fast should it react and what horsepower is available to drive my compressor/pump? What force do I need at my actuator/motor or whatever the system is expected to power? Generally, I think pneumatic systems can react more quickly but power density is lower, so if the load is very high a hydraulic system might be better. A typical shop pneumatic system might only operate at 50psi, whereas a hydraulic system can operate at 3000psi. Finally, it's also worth thinking about system safety: if a pneumatic component fails, there will be an explosive decompression, but if a hydraulic component fails, it will leak but will not explode because hydraulic fluid does not store energy, it only transmits it.
No. There are a few reasons why a pneumatic control valve can not be used with hydraulics applications. Firstly, pneumatic seals are incompatible to the chemical properties of hydraulic oils and they do not have the strength to accommodate the high pressures produced by a hydraulic system. Secondly, pneumatic valves are not designed for high pressure operation and the component would get damaged, burst or crack. Finally, the tolerances within pneumatic components would allow by-passing due to the slacker tolerances compared to hydraulic components. By-passing causes all sorts of problems by itself: Over-heating, leaking, internal structure damage of the component.
Yes there is. Pneumatic valve springs. They are metal bellows that have air in them. Their use is in replacing metal wire springs in a high-speed combustion engine. An example would be formula one engines.
Pneumatic systems are usually closed systems. Blowing up a party balloon would be one example. A cycle pump would be another, and an air-based system for moving components in pipes would be another. A windmill or a hand fan would not usually be considered to be pneumatic systems because they do not enclose the air component.

The pneumatic system controlled by electronic systems.
Pneumatic braking system utilizes compressed air to stop the motion in vehicles.
Sand blasting uses air pressure as an ejector within the blasting process. This is how the pneumatic system is used in a pneumatic sand or paint blaster.
both pneumatic & hydraulic systems are applications of fluid powers
human respiratory uses air pressure like pneumatic system does
Used in trucks and buses. This type of braking system of pneumatic and hydraulic hybrid vehicles.
