Ball Valves
Ball Valves are manufactured in 2-piece, 3-piece, ranging from 8-200 mm, having large choice of end connections and suitable for PN 16 -PN 100. The valves are available in manual, pneumatic actuated and also as jacketed versions (for temperature range - 196°C to 300°C). It is a valve that opens by turning a handle attached to a ball inside the valve. The ball 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 the flow is blocked. The handle or lever will be inline with the port position allowing to view the valve's position. These are durable and usually work to achieve perfect shutoff even after years of disuse. They are therefore an excellent choice for shutoff applications (and are often preferred to globe valves and 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. These are used extensively in industry because they are very versatile with pressures up to 10,000 psi, temperatures up to 200 Deg C. Sizes from 1/4" to 12" are readily available. They are easy to repair, operate manually or by actuators.
