A ball valve is a valve with a specifically designed spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle or lever will be inline with the port position letting you examine the valve’s position. The ball valve, along with the butterfly valve, are part of the family of quarter turn valves.
Ball valves are durable and usually work to achieve perfect shutoff. They are therefore an excellent choice for shutoff applications (and are often preferred to gate valves for this purpose). They do not offer the fine control that may be necessary in throttling applications but are sometimes used for this purpose.
Listed below are the different types of ball valves that we specialize in. If you would like to know more or want to know which one suits your system specifically, get in touch through our contact page.
