API Trunnion Ball Valve

API Trunnion Ball Valve

API Trunnion Ball Valves are mainly applied to natural gas, oil products, chemical engineering, metallurgy, city building, environment protection, pharmacy and food industries, among which the anti-sulphur series are used for long delivery pipes of natural gas that contains hydrogen sulphide mediu7m, a lot of impurity and corrosive substances.

Descriptions of API Trunnion Ball Valve are:1)Size: 1/2"- 48" ;2)Pressure: Class 150lb to 2500lb ;3)Material: WCB, CF3, CF3M, CF8, CF8M etc. ;4)Dsign & Manufacture Standard: BS5352, API 597, API 6D ;5)Face To Face standard: ASME B16.5 ;6)End Connection Standard: ASME/ANSI B16.5A, ASME B16.47 ASME B16.25 ;7)Test and inspection: API598 ;8)Operated Way: Lever, gear, actuator.

Ball valves 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. 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 "see" the valve's position. The ball valve, along with the butterfly valve and plug valve, are part of the family of quarter turn valves.
