Ball valves and gate valves
Thread Content
I would like to ask the experts: for the root valve of the combustible gas oxygen content analyzer, the manufacturer requires a ball valve and will not accept gate valves. The project timeline is quite tight at the moment; why can’t a gate valve be used instead? Thank you
What was said upstairs is absolutely correct – ball valves are easy to operate and convenient to open and close.
For the second floor, ball valves are recommended as the root valves for gases that are flammable, mainly because they can be opened and closed quickly during operation.
If rapid shutdown is not required, any method will do; it can only be said that ball valves are better than gate valves. If quick shut-off is required, then a ball valve should be chosen.
It is better to use ball valves; gate valves are not easy to operate in applications that require constant opening or closing
Ball valves open and close quickly, making them ideal for use in hazardous environments such as those involving gases. They also have good wear resistance, allowing for long-term use. How long is the shortest delivery time you can offer?
Whether it is a ball valve or a gate valve, its sealing performance must be good; it is best to use two valves
It is difficult to ensure that the gate of a gate valve and its stem have the same electrical charge. Even with fully rubber-lined gates used in water treatment systems, there is still a gap at the junction between the stem and the gate. Where there is a gap, collisions can occur, and could electrical sparks be generated as a result of such collisions? It’s hard to say. Ball valves can achieve soft sealing; furthermore, a hole can be made at the bottom of the valve stem, and a spring along with a steel ball can be inserted there, ensuring that the valve stem remains in constant contact with the ball. This prevents the formation of a potential difference and thus avoids the generation of electric sparks. If the medium is oxygen, gate valves cannot be used.
