Problems with ball valves for tracks
Thread Content
This post was last edited by *lihuagong on 2015-8-18 08:41. May I ask everyone, what is the difference between floating ball valves and track ball valves, and what are the advantages of using track ball valves? Pneumatic ball valves are required. I see that pneumatic gate valves and pneumatic globe valves are similar; what is their sealing performance like? Could you recommend a few manufacturers and product documents for reference? Thank you.
Are there any manufacturers that produce track ball valves?
Orbital ball valve. To achieve a frictionless operation, when the valve is opened, the valve stem first rises to disengage the valve ball from the valve seat, and then drives the valve ball to rotate into the open position ； When the valve is closed, the valve stem causes the valve ball to rotate without making contact with the valve seat; then the valve stem descends, pressing the valve ball tightly against the valve seat. In simple terms, it means less friction and a longer service life
I want to use a pneumatic ball valve; since it has a ball inside, I noticed that pneumatic ball valves look similar to pneumatic gate valves and pneumatic globe valves. However, the internal structures of gate valves, globe valves, and ball valves are different. Pneumatic gate valves and globe valves move up and down, so shouldn’t pneumatic ball valves operate by moving left and right?
A track ball valve features a track groove on its valve stem; it doesn’t close from side to side but rather up and down. Sealing is achieved by applying pressure to the sides when the valve is closed. I haven’t used a track ball valve myself, but you can find 3D demonstration videos of Suchu and Jiangnan’s track ball valves online, which provide clear explanations. Just search for \"track ball valve\" to find them. I hope this helps you
