Trunnion mounted ball valve

Trunnion Mounted Ball Valve. A short shaft like an extension that called trunnion set in the body. You can see this in the image. In this design steam and ball work as a single unit.

The FK76C split-body, full-bore, trunnion-mounted ball valve represents the highest standards in valve technology. Its superfinefinishe trunnion - mounted ball design is just one of its many important design features.

If process uptime and valve performance are important to you, then look no further for all your valve needs. Designe tested and manufactured to provide peak performance in your process Our trunnion mounted ball valves are utilized in some of the most demanding processes in virtually every industry. The result is the highest-quality and most competitively-priced trunnion-mounted ball valve available. It embodies all the quality, Performance, value and safety features required for critical applications.

SCV Valve manufactures some of the most dependable cast and forged steel Ball Valves in the industry. Our products are manufactured and tested in accordance with respective API, ASME, and ANSI standards. Valves of sizes above inches have a cast body (the most common grades are ASTM A2WCB for high temp.

service, ASTM A3for low-temperature service and ASTM A3CF CF8M for cast stainless steel valves ). A floating ball valve is one where the ball is not held in place by a trunnion.

What is the plural of trunnion? Find trunnion mounted ball valve Made in China at Wholesale Prices. The robust design tolerates the heavy loads applied to the valve trim that result from of large sizes, high pressures and dynamic temperature cycles. Double Block and Blee Ball Needle Ball configuration, trunnion mounted valve manifold utilising soft and metal to metal seating, using the latest in piston seat design, with flange to body connection for superior, bubble tight sealing capabilities at both high pressures and temperatures. Warren Valve maintains the highest quality standards in the industry.

Our valves are subject to rigorous inspections throughout the manufacturing process. These comprehensive evaluations include on-site audits, inspection at the source, receiving inspections and destructive material testing. Gn The MJ Ball Valve is a trunnion mounted design.

The trunnions are fitted into TFE lined bearing blocks supported within the valve body. The key difference beteween a floating ball valve and a trunnion mounted ball valve is how each achieves a line seal. EMERGENCY SEALS For trunnion mounted ball valve size NPS (DN 150) and above, it comes with provisions for sealant injection on both the stem and seat while for sizes NPS (DN 125) and below on body cavity.

Similarly, trunnion mounted ball design is also capable of bi-directional sealing. An advantage of trunnion ball design over floating ball is the lower operating torque of the ball. This is particularly advantageous when the ball valve is actuated because it reduce the size of the actuator and hence the overall costs of the valve actuation.

To reduce torque even at high operating ranges, the trunnion - mounted stems absorb line pressure and minimize friction between balls and seats. We manufacture all of our three-piece and two-piece trunnion ball valves to the highest engineering and quality standards. Argus FK76M trunnion mounted ball valves are engineered to deliver long-lasting, tight shut-off performance in oil and gas, petrochemical and chemical industry applications.

It features a modular design that allows simplified adaptation to diverse safety, emissions and performance requirements. Since the ball is not held in place by a tight fitting seal arrangement, operating torque tends to be lower for comparably sized trunnion mount valves , when compared to floating ball valves. On of the brochure included below, the exploded. The functional difference between trunnion mounted ball valves and floating ball valve designs involves the operating pressure characteristics, with trunnion styles having better sealing for low pressure applications because they are not relying on system pressure to aid with sealing. The operating characteristics are similar for all trunnion - mounted ball valves.

As the ball of the floating ball valve is floating, so under the pressure of the medium, the floating ball will move and against the downstream seat. The ball of the trunnion ball valve cannot be move so the two sides of the trunnion ball valve both must be sealed.
