Trunnion Mounted Ball Valve Weight Control
Available in seat pocket, seal areas and all wetted parts. 607 Fire test for Soft Seated Quarter Turn Valves. High pressure applications. Below, you'll find further information on our trunnion ball valve materials, applications, and more. Size range: 2-24 inches. Forged Body Trunnion Mounted Ball Valves. 598 Valve Inspection and Test. The valve has two seats, each providing a seal against pressure separately. 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. Advantages of a ball valve include Fast shut off, only a 90-degree turn required to close the valve. We manufacture all of our three-piece and two-piece trunnion ball valves to the highest engineering and quality standards. Full and Reduced Bore. Self-lubricating steel bearings. For example, these designs offer a standard feature of a secondary emergency sealant injection system that provides temporary seals to otherwise damaged areas.

Trunnion Mounted Ball Valve Weight Control
TVC Trunnion-Mounted Ball Valves (TMBV) are engineered to the latest API, ISO, and ASME standards—manufactured using best-in-class materials and technologies. Soft seat or metal seat design critical service. The result is the highest-quality and most competitively-priced trunnion-mounted ball valve available. SP 45 Bypass and Drain Connection Standard. The advanced, integrated design offers numerous advantages over traditional single-isolation block valves. In a floating ball valve, the ball is only connected to the stem, and is therefore called floating. Why Trunnion Ball Valve? Warren Valve offers a 2"–48" forged steel trunnion mounted ball valves to meet the industry's strictest specifications. This is illustrated in Figure 1 and highlighted by a red box.

For example, we offer Inconel 625 weld overlays that provide superior protection in challenging conditions. Learn more about ball valves in our extensive ball valve guide. Pressure class: ANSI 150-2500. Trunnion-Mounted Ball Valves. Double Block and Bleed. It is necessary to vent/bleed the pressure when the pressure in the ball becomes high enough. The fluid remains trapped within the ball, which creates a resultant pressure in the ball. Trunnion mounted ball valves are fitted with spring loaded seats. 33 times the design pressure rating for the ball valves. Additionally, this design reduces torque required to stroke the valve, making a trunnion design ideal for automated ball valve applications. High-head direct mount with two-inch square operating nut. According to API 6D specifications, the venting/bleeding is required at a pressure of less than 1.
Trunnion Mounted Ball Valve Weight Limits
In one study, overlay and non-overlay valves were compared from the same worksite after six years of field service. This is advantageous since it will maintain a proper seal on both sides and there is no added torque to the stem. All TVC TMBV address all of the safety, quality, and design issues important for ensuring consistent field performance and environmental protection. For high pressure applications, a trunnion ball valve is the ideal ball valve design type. 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. However, several critical projects need to vent at a pressure less than 1.
Special applications: metal-seated, alloy overlays, high/low temperatures, cryogenic services. 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. 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. Literature and data available on request. In addition, the torque on the stem is also increased. API 6D gives basic design, dimensions, and testing standards for the trunnion valve. BS British Standard.
