Trunnion mounted ball valve weight. Warren Valve offers a 2"–48" forged steel trunnion mounted ball valves to meet the industry's strictest specifications. Mill test reports are always available. Trunnion mounted ball valve weight rating. A trunnion ball valve is designed by API608 or API 6D and complies with several other industry standards. The valve has two seats, each providing a seal against pressure separately. The advanced, integrated design offers numerous advantages over traditional single-isolation block valves. We manufacture all of our three-piece and two-piece trunnion ball valves to the highest engineering and quality standards.

Trunnion Mounted Ball Valve Weight Watchers

Trunnion ball valves are quarter-turn valves used to stop or start the flow of a media in a pipe. Unfortunately the ball valve will need high pressure to create an effective seal, which would render them ineffective in low pressure systems. Pressure class: ANSI 150-2500. The fluid remains trapped within the ball, which creates a resultant pressure in the ball. 33 times the design pressure rating for the ball valves. For a DBB trunnion mounted ball valve, when the valve is in the closed position, and the fluid comes from upstream, it pushes the seat against the ball to release the sealing. Extended valve life at a fraction of the cost of a solid corrosion-resistant alloy valve. American Petroleum Institute (API) 6D design. Trunnion-Mounted Ball Valves. Trunnion Ball Valve - How They Work. When the ball is rotated 90-degree, the bore becomes perpendicular to the flow path, meaning the valve is closed, and fluid cannot pass. NACE/fire-safe design.

MSS Manufacturers Standardization Society. Our tandem valves are designed to the highest manufacturing standard including American Petroleum Institute (API) and American National Standards Institute (ANSI). For a trunnion ball valve with a bleed function, the pressure in the ball pushes the seat back as the spring behind the seat compresses, and there is vent/bleeding between the sealing surfaces. Contact us for more information. The pressure within the ball rises when the temperature in the ball becomes higher. Our products include ANSI Classes 150 – 2500 in carbon steel bodies with electroless nickel plating or stainless steel trim, as well as full stainless steel body and trim. All TVC TMBV address all of the safety, quality, and design issues important for ensuring consistent field performance and environmental protection. Within a trunnion ball valve the ball connects to the stem on one end and on the other end a shaft called the trunnion. Trunnion mounted ball valve weight scale. High pressure applications. Size range: 2-24 inches. 6D Specification for Pipeline Valves.

Trunnion Mounted Ball Valve Weight Scale

We offer a full range of materials in carbon, alloy and stainless steel from general to severe in application, including Sub Sea. Advantages of a ball valve include Fast shut off, only a 90-degree turn required to close the valve. This is illustrated in Figure 1 and highlighted by a red box. Each detail is designed to minimize maintenance even under extreme operating conditions, significantly reducing operational cost over the total valve life. They're designed to provide superior performance in a variety of applications, including offshore platforms, oil, gas, and other liquids pipelines, tank farms, meter stations, chemical processing plants and refineries. Trunnion mounted ball valve weight watchers. Lower operational costs. The Ball Valve provides tight seal, even after long periods, utilizing soft sealing components.

SP 25 Standard Marking System for Valves, Fittings, Flanges and Unions. Bolted Body Construction. The result is the highest-quality and most competitively-priced trunnion-mounted ball valve available. The opened or closed state of the valve can be easily detected by position of the handle. Tandem (Double Ball) Valves. Focusing the full impact of oil and gas line media into the upstream valve permits the downstream valve to provide tight, bubble-tight shutoff and isolation that outperforms single valve systems. Below Ground Extension. A ball valve uses a rotating ball and a stem to provide on/off flow control. Size range: two to 12 inches. Trunnion-Mounted Ball Valves. API American Petroleum Institute.

Trunnion Mounted Ball Valve Weight Rating

Special applications: metal-seated, alloy overlays, high/low temperatures, cryogenic services. Full or reduced port. API 6D gives basic design, dimensions, and testing standards for the trunnion valve. Due to this design change, the ball is held firmly in place. Soft seat or metal seat design critical service. Body material: carbon steel (American Society for Testing and Materials A216 WCB/ WCC). The API 6D standard also gives the standard weights of trunnion ball valves corresponding to different bore sizes and body dimensions. To learn more about making the right selection of ball valve for your application, read our ball valve selection technical article! 5 Steel Pipe Flanges and Flanged Fittings. Standard lengths: 48-, 60-, 72-, 84- and 96-inch (custom high-head lengths available upon request). ANSI Class 150, 300, and 600. Below, you'll find further information on our trunnion ball valve materials, applications, and more. Features:Three-Piece Trunnion (Metal-Seated) Ball Valve. ISO 9001-2000 Quality Systems for Design/Development, Production, Installation, Servicing.

National Association of Corrosion Engineers (NACE)/fire-safe design. Therefore a trunnion ball valve can block both the upstream and downstream sides of the working area and then vent (bleed) any pressure that remains in the piping and valve. Pinion shaft extension with gear and miter box, upright orientation. This leads to a lower operating torque, and subsequently eliminates the need for a large actuator. Double block and bleed (DBB) is the process of shutting a pipe section on both sides of the valve rather than just one.
