Additionally, this design reduces torque required to stroke the valve, making a trunnion design ideal for automated ball valve applications. Body material: carbon steel (American Society for Testing and Materials A216 WCB/ WCC). The unique design integrates double-valve functionality into a single body and creates true double block-and-bleed sealing. Forum's full catalog of PBV valve solutions offer a variety of stainless steel and high-nickel alloy weld overlays for internal surfaces. To learn more about making the right selection of ball valve for your application, read our ball valve selection technical article! In addition, the torque on the stem is also increased.

We offer a full range of materials in carbon, alloy and stainless steel from general to severe in application, including Sub Sea. Double block and bleed and emergency sealant injection fittings are standard, along with NACE and fire-safe. Trunnion Ball Valve - How They Work. A trunnion mounted ball valve provides lower operational costs due to the fact that any additional pressure on the valve is absorbed by the trunnion and the stem. 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. 10 Face to Face and End to End Dimensions of Ferrous Valves.
Size range: two to 12 inches. Pinion shaft extension with gear and miter box, upright orientation. The advanced, integrated design offers numerous advantages over traditional single-isolation block valves. 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. A separate field study tested valves with seat pockets manufactured using Alloy 316L – a molybdenum-bearing austenitic stainless steel – and ENP plating. High direct mount with gear. Size range: 2-24 inches. All TVC TMBV address all of the safety, quality, and design issues important for ensuring consistent field performance and environmental protection. Materials: 316 stainless steel or Inconel nickel-chromium alloys. Trunnion mounted ball valve weight watchers. This makes trunnion design ball valves suitable for larger-bore and higher-pressure operations. 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. The result is added protection for vulnerable areas and improved performance even within the most hostile environments. The result is the highest-quality and most competitively-priced trunnion-mounted ball valve available.
API 6D gives basic design, dimensions, and testing standards for the trunnion valve. In a floating ball valve the pressure forces the ball against the seats, which creates a seal. High-head direct mount with two-inch square operating nut. NACE/fire-safe design.
Double block and bleed (DBB) is the process of shutting a pipe section on both sides of the valve rather than just one. Trunnion-Mounted Ball Valves. However, several critical projects need to vent at a pressure less than 1. Below, you'll find further information on our trunnion ball valve materials, applications, and more. A double block and bleed (DBB) is often used for stricter isolation of process fluid from other equipment. High pressure applications. With any questions you have about this product or our trunnion-mounted Ball valve manufacturer service. Bolted Body Construction. Trunnion mounted ball valve weight calculator. 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. ISO 5211 Topworks for Mounting Dimensions. Trunnion ball valves are quarter-turn valves used to stop or start the flow of a media in a pipe. Standard lengths: 48-, 60-, 72-, 84- and 96-inch (custom high-head lengths available upon request). SP 25 Standard Marking System for Valves, Fittings, Flanges and Unions.
For high pressure applications, a trunnion ball valve is the ideal ball valve design type. When the pipeline is under pressure, the trunnion ball valve is closed. When the valve is positioned where the bore is aligned in the same direction as the pipeline, it is in the open position, and fluid can pass downstream. ANSI Class 150, 300, and 600. In the trunnion valve design, the ball is not floating as it is connected to the trunnion. It usually consists of two trunnion ball valves that act as block valves and a bleed valve (usually ball or needle valve) to a safe location, consistent with local environmental regulations. BS 5351 Steel Ball Valves for the Petroleum, Petrochemical, and Allied Industries. Trunnion mounted ball valve weight loss pills. All of our weld overlays are designed in accordance with standards from the American Society of Mechanical Engineers (ASME). Contact us for more information. Trunnion ball valve advantages. TVC Trunnion-Mounted Ball Valves (TMBV) are engineered to the latest API, ISO, and ASME standards—manufactured using best-in-class materials and technologies. After cleaning and refitting with new seals, the valves were returned to service for significant equipment savings.
Literature and data available on request. In the floating ball valves the ball has some freedom of movement. A ball valve uses a rotating ball and a stem to provide on/off flow control. ISO 15848-1 Compliance. For example, these designs offer a standard feature of a secondary emergency sealant injection system that provides temporary seals to otherwise damaged areas. 1 times the originally designed pressure. 598 Valve Inspection and Test. Self-lubricating steel bearings. The most common type of ball valve has a "free floating" design, so the trunnion type is a design change. Reliable, bubble-tight shut off is essential for isolation valves, but hostile service conditions – corrosive or abrasive environments and high pressures – place heavy demands on valve performance.
For example, we offer Inconel 625 weld overlays that provide superior protection in challenging conditions. Why Trunnion Ball Valve? Body materials: carbon steel (A105/LF2) and 316 stainless steel. ASME American Society of Mechanical Engineers. Lower operational costs. Therefore, for higher pressure applications a trunnion ball valve will provide better sealing and require less torque to turn. Trim: electroless nickel plating (316 stainless steel). API Standards: 6D & 6A. When the ball is rotated 90-degree, the bore becomes perpendicular to the flow path, meaning the valve is closed, and fluid cannot pass. Weld Overlay Internals. The API 6D standard also gives the standard weights of trunnion ball valves corresponding to different bore sizes and body dimensions. This design provides a positive seal on both downstream and upstream seats, regardless of pressure, allowing for Double Block and Bleed, or Double Isolation and Bleed function.
