In the floating ball valves the ball has some freedom of movement. 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. The carbon steel balls with electroless nickel plating (ENP) were completely degraded from the heavy brine environment, while the Inconel overlay valves showed zero signs of pitting or corrosion. Trunnion mounted ball valves are fitted with spring loaded seats.

Trunnion Mounted Ball Valve Weight Limit
Welding in accordance with ASME standard BPV Section 9. Spring-Loaded Seats. SP 25 Standard Marking System for Valves, Fittings, Flanges and Unions. Our commitment to quality is second-to-none and exceeds industry standards so that our customers receive only the best products like trunnion mounted ball valves available. Soft seat or metal seat design critical service. Our tandem valves are designed to the highest manufacturing standard including American Petroleum Institute (API) and American National Standards Institute (ANSI).
Trunnion Mounted Ball Valve Weight Control
Pressure class: American National Standards Institute (ANSI) 150-2500. Trunnion mounted ball valves are effective in both low and high pressure situations. View our online selection of ball valves! 607 Fire test for Soft Seated Quarter Turn Valves. Trunnion Ball Valve - How They Work. 8 Gas Transmission and Distribution Piping Systems. Warren Valve offers a 2"–48" forged steel trunnion mounted ball valves to meet the industry's strictest specifications. This is the point where the trunnion design offers a solution.
Trunnion Mounted Ball Valve Weight Set
American Petroleum Institute (API) 6D design. Each detail is designed to minimize maintenance even under extreme operating conditions, significantly reducing operational cost over the total valve life. Therefore, for higher pressure applications a trunnion ball valve will provide better sealing and require less torque to turn. Double block and bleed and emergency sealant injection fittings are standard, along with NACE and fire-safe. After cleaning and refitting with new seals, the valves were returned to service for significant equipment savings. Body material: carbon steel (dual-rated A105/LF2). The API 6D standard also gives the standard weights of trunnion ball valves corresponding to different bore sizes and body dimensions. Figure 1: Free floating ball valve (left) and a trunnion mounted ball valve (right). MSS Manufacturers Standardization Society. Full and Reduced Bore. Available in seat pocket, seal areas and all wetted parts. Why Trunnion Ball Valve? The result is the highest-quality and most competitively-priced trunnion-mounted ball valve available. Literature and data available on request.
Trunnion Mounted Ball Valve Weight Limits
Trunnion mounted ball valve weight. Cost-effective options for ball valves in highly corrosive or erosive service. BS British Standard. After extended hard use, field experts found no evidence of corrosion in the seat pockets or process-wetted area.
Trunnion Mounted Ball Valve Manufacturers
In a floating ball valve the pressure forces the ball against the seats, which creates a seal. In one study, overlay and non-overlay valves were compared from the same worksite after six years of field service. Materials: 316 stainless steel or Inconel nickel-chromium alloys. 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. This is illustrated in Figure 1 and highlighted by a red box. 10 Face to Face and End to End Dimensions of Ferrous Valves. Size Range: 2" – 64". Special applications: metal-seated, alloy overlays, high/low temperatures, cryogenic services. Forum's full catalog of PBV valve solutions offer a variety of stainless steel and high-nickel alloy weld overlays for internal surfaces. The valve has two seats, each providing a seal against pressure separately.
Trunnion Mounted Ball Valve Weight Definition
When the ball is rotated 90-degree, the bore becomes perpendicular to the flow path, meaning the valve is closed, and fluid cannot pass. Figure 2: A cross section of a trunnion ball valve, clearly showing the trunnion (A), and spring mounted seats (B). Full or reduced port. Trunnion-mounted ball design feature a "trunnion" anchoring at the top and bottom of the ball. Series T Carbon Steel. Double block and bleed (DBB) is the process of shutting a pipe section on both sides of the valve rather than just one. 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. 4 Liquid Petroleum Transportation Piping Systems. When the pipeline is under pressure, the trunnion ball valve is closed.
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. We manufacture all of our three-piece and two-piece trunnion ball valves to the highest engineering and quality standards. Onshore or offshore, Forum's PBV® tandem ball valves withstand the most hostile hydrocarbon operating environments and provide positive shutoff for enhanced safety. In low or no-pressure situations the spring-loaded seats will create a seal, while also working for high pressure applications. 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. Standard lengths: 48-, 60-, 72-, 84- and 96-inch (custom high-head lengths available upon request). SP 45 Bypass and Drain Connection Standard.
The advanced, integrated design offers numerous advantages over traditional single-isolation block valves. Contact us for more information. A double block and bleed (DBB) is often used for stricter isolation of process fluid from other equipment. 598 Valve Inspection and Test. Features:Three-Piece Trunnion (Metal-Seated) Ball Valve.
6D Specification for Pipeline Valves. MR0175 Sulfide Stress Cracking Resistant Metallic Materials for Oilfield Equipment. Tiger Valve Company (TVC) is a trunnion-mounted ball valve manufacturer for the TL and TB Series. A separate field study tested valves with seat pockets manufactured using Alloy 316L – a molybdenum-bearing austenitic stainless steel – and ENP plating. The most common type of ball valve has a "free floating" design, so the trunnion type is a design change.
