Trunnion Mounted Ball Valve Weight

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. Our tandem valves are designed to the highest manufacturing standard including American Petroleum Institute (API) and American National Standards Institute (ANSI). 1 times the originally designed pressure. 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. In the trunnion valve design, the ball is not floating as it is connected to the trunnion. GWC produces a full line of API-6D Trunnion Mounted Ball valves in both two/three Piece Forged. The advanced, integrated design offers numerous advantages over traditional single-isolation block valves. Why Trunnion Ball Valve? A separate field study tested valves with seat pockets manufactured using Alloy 316L – a molybdenum-bearing austenitic stainless steel – and ENP plating.

Metal Seated Trunnion Mounted Ball Valve Pdf

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. 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. Materials: 316 stainless steel or Inconel nickel-chromium alloys. The most common type of ball valve has a "free floating" design, so the trunnion type is a design change. Trunnion mounted ball valves are effective in both low and high pressure situations. For high pressure applications, a trunnion ball valve is the ideal ball valve design type. 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 Index

Gear Operated Trunnion Ball Valve. This makes trunnion design ball valves suitable for larger-bore and higher-pressure operations. Full and Reduced Bore. Forum's full catalog of PBV valve solutions offer a variety of stainless steel and high-nickel alloy weld overlays for internal surfaces. API 6D gives basic design, dimensions, and testing standards for the trunnion valve. After cleaning and refitting with new seals, the valves were returned to service for significant equipment savings.

Trunnion Mounted Ball Valve Torque

Mill test reports are always available. 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. We offer a full range of materials in carbon, alloy and stainless steel from general to severe in application, including Sub Sea. When the pipeline is under pressure, the trunnion ball valve is closed. Contact us for more information. ISO International Organization for Standardization. Special applications: metal-seated, alloy overlays, high/low temperatures, cryogenic services. Additionally, this design reduces torque required to stroke the valve, making a trunnion design ideal for automated ball valve applications. 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.

Trunnion Mounted Ball Valve Drawing

Double Block and Bleed. Our entire valve catalog offers easy field service and numerous options such as stem extensions, locking devices, transition pieces and direct-mounted actuation. Full or reduced port. Literature and data available on request.

Trunnion Mounted Ball Valve Weight Calculator

Firesafe to API-607/6FA. This is illustrated in Figure 1 and highlighted by a red box. Body material: carbon steel (American Society for Testing and Materials A216 WCB/ WCC). Soft seat or metal seat design critical service. Due to this design change, the ball is held firmly in place.

The pressure within the ball rises when the temperature in the ball becomes higher. Flanged ends, weld ends, flanged-X weld ends. However, several critical projects need to vent at a pressure less than 1. In the floating ball valves the ball has some freedom of movement. For example, these designs offer a standard feature of a secondary emergency sealant injection system that provides temporary seals to otherwise damaged areas.
