Are oil-operated valves the same as pneumatic valves?
Thread Content
I saw that a hydraulic pressure control valve is operated by hydraulic power; is its principle the same as that of a pneumatic valve? Who has used it? Please share your experience. This valve uses the oil pressure after passing through the oil filter as the power signal.
I see now; it works in the same way as a pneumatic valve, that is, oil pressure is used to operate the valve, haha.
Self-taught, haha – just putting together words and numbers
That’s how masters are made! !
There are such hydraulic control valves, which are generally used in applications requiring high torque or rapid closing
The working principles of hydraulic valves and pneumatic valves are basically the same; both use two-position five-way valves, with the only difference being the medium used. Oil-free air separation is rarely seen, but it is still used in some high-pressure applications where rapid shutdown is required. I worked on a hydraulic system that was capable of handling 200 kilograms of force; it’s much more complex than pneumatic systems. It has an oil reservoir, and high standards are required regarding the quality of the oil – even a small amount of dirt can cause blockages.
Oil is much less compressible than gas, so using oil to control valves results in more stable and faster operation. The emergency shut-off valves on the turbines I used to operate were controlled by oil.
