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. High direct mount with gear. 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 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. A trunnion ball valve is designed by API608 or API 6D and complies with several other industry standards. Features:Three-Piece Trunnion (Metal-Seated) Ball Valve. In a floating ball valve, the ball is only connected to the stem, and is therefore called floating.
NACE/fire-safe design. 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. 33 times the design pressure rating for the ball valves. ISO International Organization for Standardization. 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. Each detail is designed to minimize maintenance even under extreme operating conditions, significantly reducing operational cost over the total valve life. 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. National Association of Corrosion Engineers (NACE)/fire-safe design.
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. With any questions you have about this product or our trunnion-mounted Ball valve manufacturer service. The pressure within the ball rises when the temperature in the ball becomes higher. Trim: electroless nickel plating (316 stainless steel). Firesafe to API-607/6FA. Size range: 2-24 inches. SP 45 Bypass and Drain Connection Standard.
The Ball Valve provides tight seal, even after long periods, utilizing soft sealing components. 4 Liquid Petroleum Transportation Piping Systems. Unfortunately the ball valve will need high pressure to create an effective seal, which would render them ineffective in low pressure systems. Materials: 316 stainless steel or Inconel nickel-chromium alloys. 10 Face to Face and End to End Dimensions of Ferrous Valves. BS British Standard. We offer a full range of materials in carbon, alloy and stainless steel from general to severe in application, including Sub Sea.
Features: Two-Piece Trunnion Ball Valves. The valve has two seats, each providing a seal against pressure separately. Mill test reports are always available. 5 Steel Pipe Flanges and Flanged Fittings. This is illustrated in Figure 1 and highlighted by a red box. In the trunnion valve design, the ball is not floating as it is connected to the trunnion. Additionally, this design reduces torque required to stroke the valve, making a trunnion design ideal for automated ball valve applications. API American Petroleum Institute. Trunnion Ball Valve - How They Work. Our tandem valves are designed to the highest manufacturing standard including American Petroleum Institute (API) and American National Standards Institute (ANSI). In one study, overlay and non-overlay valves were compared from the same worksite after six years of field service. Cost-effective options for ball valves in highly corrosive or erosive service. Special applications: metal-seated, alloy overlays, high/low temperatures, cryogenic services. In low or no-pressure situations the spring-loaded seats will create a seal, while also working for high pressure applications.
Below, you'll find further information on our trunnion ball valve materials, applications, and more. 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. 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. In a floating ball valve the pressure forces the ball against the seats, which creates a seal. Series T Carbon Steel. After extended hard use, field experts found no evidence of corrosion in the seat pockets or process-wetted area. 6D Specification for Pipeline Valves. Therefore, for higher pressure applications a trunnion ball valve will provide better sealing and require less torque to turn. Onshore or offshore, Forum's PBV® tandem ball valves withstand the most hostile hydrocarbon operating environments and provide positive shutoff for enhanced safety. Figure 2: A cross section of a trunnion ball valve, clearly showing the trunnion (A), and spring mounted seats (B). Pressure class: American National Standards Institute (ANSI) 150-2500.
When the pipeline is under pressure, the trunnion ball valve is closed. 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. The most common type of ball valve has a "free floating" design, so the trunnion type is a design change. The API 6D standard also gives the standard weights of trunnion ball valves corresponding to different bore sizes and body dimensions.
MSS Manufacturers Standardization Society. According to API 6D specifications, the venting/bleeding is required at a pressure of less than 1. Full or reduced port. API Standards: 6D & 6A. Spring-Loaded Seats.
Welding in accordance with ASME standard BPV Section 9. API 6D gives basic design, dimensions, and testing standards for the trunnion valve.
