Trunnion Mounted Ball Valve Drawing

ANSI Class 900 (2, 200 PSI WP). Trunnion ball valves are quarter-turn valves used to stop or start the flow of a media in a pipe. SP 25 Standard Marking System for Valves, Fittings, Flanges and Unions. Gear Operated Trunnion Ball Valve. ANSI Class 150, 300, and 600. 607 Fire test for Soft Seated Quarter Turn Valves. Trunnion-Mounted Ball Valve Manufacturer | Tiger Valve. The fluid remains trapped within the ball, which creates a resultant pressure in the ball. Trim: electroless nickel plating (316 stainless steel). According to API 6D specifications, the venting/bleeding is required at a pressure of less than 1.

SP 45 Bypass and Drain Connection Standard. ISO International Organization for Standardization. Features:Three-Piece Trunnion (Metal-Seated) Ball Valve. Mill test reports are always available. This leads to a lower operating torque, and subsequently eliminates the need for a large actuator. Trunnion mounted ball valve weight loss. The result is added protection for vulnerable areas and improved performance even within the most hostile environments. This is the point where the trunnion design offers a solution. Tiger Valve Company (TVC) is a trunnion-mounted ball valve manufacturer for the TL and TB Series. Figure 2: A cross section of a trunnion ball valve, clearly showing the trunnion (A), and spring mounted seats (B). Double Block and Bleed. Standard lengths: 48-, 60-, 72-, 84- and 96-inch (custom high-head lengths available upon request). Pinion shaft extension with gear and miter box, upright orientation. 33 times the design pressure rating for the ball valves.

National Association of Corrosion Engineers (NACE)/fire-safe design. Bolted Body Construction. Forum's valve manufacturing also leverages a wide variety of certified materials that resist sulfide stress cracking and increase performance in corrosive environments. NACE National Association of Corrosion Engineers. Advantages of a ball valve include Fast shut off, only a 90-degree turn required to close the valve. In a floating ball valve, the ball is only connected to the stem, and is therefore called floating. To learn more about making the right selection of ball valve for your application, read our ball valve selection technical article! This is advantageous since it will maintain a proper seal on both sides and there is no added torque to the stem. Trunnion-Mounted Ball Valves. Trunnion ball valves have many different advantages over free floating valves, they are suitable for low, and high-pressure applications, and offer lower operational costs then free floating ball valves. 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. Weld Overlay Internals. Size range: two to 12 inches. Onshore or offshore, Forum's PBV® tandem ball valves withstand the most hostile hydrocarbon operating environments and provide positive shutoff for enhanced safety.

Trunnion Mounted Ball Valve Weight Index

1 times the originally designed pressure. We manufacture all of our three-piece and two-piece trunnion ball valves to the highest engineering and quality standards. Trunnion mounted ball valve drawing. Materials: 316 stainless steel or Inconel nickel-chromium alloys. Soft seat or metal seat design critical service. API 6D gives basic design, dimensions, and testing standards for the trunnion valve. Available in seat pocket, seal areas and all wetted parts. The Ball Valve provides tight seal, even after long periods, utilizing soft sealing components.

Full and Reduced Bore. 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. 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. Tight shutoff is essential during oil and gas applications, and the superior anchoring of Forum's PBV® trunnion-mounted ball valves make them especially well-suited for large, high-pressure valve applications. The API 6D standard also gives the standard weights of trunnion ball valves corresponding to different bore sizes and body dimensions. BS 5351 Steel Ball Valves for the Petroleum, Petrochemical, and Allied Industries. View our online selection of ball valves! Trunnion mounted ball valve weight index. Therefore, for higher pressure applications a trunnion ball valve will provide better sealing and require less torque to turn. Severe service areas can create difficult operating conditions that significantly reduce the working lifespan of oil and gas valves. Body material: carbon steel (dual-rated A105/LF2). Learn more about ball valves in our extensive ball valve guide. During use, the ball floats slightly downstream against the seat ring and creates a sealing only on one side of the valve. 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. After extended hard use, field experts found no evidence of corrosion in the seat pockets or process-wetted area.

American Petroleum Institute (API) 6D design. We offer a full range of materials in carbon, alloy and stainless steel from general to severe in application, including Sub Sea. In the floating ball valves the ball has some freedom of movement. Correct material selection is essential to balance harsh effects from total system pressure, application temperature and elemental sulfur/chloride content. A double block and bleed (DBB) is often used for stricter isolation of process fluid from other equipment. Size Range: 2" – 64".

Trunnion Mounted Ball Valve Weight Loss

API American Petroleum Institute. The result is the highest-quality and most competitively-priced trunnion-mounted ball valve available. The advanced, integrated design offers numerous advantages over traditional single-isolation block valves. A trunnion ball valve is designed by API608 or API 6D and complies with several other industry standards. It is necessary to vent/bleed the pressure when the pressure in the ball becomes high enough. A ball valve uses a rotating ball and a stem to provide on/off flow control. Literature and data available on request. Cost-effective options for ball valves in highly corrosive or erosive service.

API Standards: 6D & 6A. This is illustrated in Figure 1 and highlighted by a red box. The unique design integrates double-valve functionality into a single body and creates true double block-and-bleed sealing. ISO 15848-1 Compliance.

Each detail is designed to minimize maintenance even under extreme operating conditions, significantly reducing operational cost over the total valve life. Additionally, this design reduces torque required to stroke the valve, making a trunnion design ideal for automated ball valve applications.
