The centerline butterfly valve is symmetrically designed, with the center axis of the valve plate coinciding with the axis of the pipeline. It achieves sealing by the compression deformation of the elastic valve seat (usually rubber).

Electric actuators utilize different methods for motion transmission. This text compares two distinct types: Threaded Drives and Three-Jaw Drives, highlighting key differences in operation, construction, and application.

Ball valves are everywhere—in your home, your workplace, and nearly every industrial plant or pipeline system you can think of. But unless you’re in the field, you might not realize how essential these simple-looking components really are. So what is a ball valve used for? That’s what this guide will break down clearly, with no jargon and no fluff.

A floating ball valve is a type of quarter-turn valve in which the ball is not physically fixed by a stem or shaft at both ends. Instead, it “floats” within the valve body, held in place only by the pressure of the valve seats.

If you’re working with a 3/8″ ball valve and it starts to leak or squeak, chances are the issue lies with a tiny yet crucial part: the O-ring. But here’s the tricky part—finding the right O-ring isn’t always as simple as grabbing “the 3/8 one.”

Do you sometimes feel that ordinary valves are not easy to use? The seal is not tight enough? It is difficult to open and close? Or are you worried that it can't withstand high temperature and high pressure environment? Don't worry, today I will introduce to you a "powerful player" in the pipeline control industry-flange eccentric butterfly valve. It is not an ordinary butterfly valve, but a master with its own "eccentric" skills!
