API-6A Trunnion Mounted Ball Valves

API-6A Trunnion Mounted Ball Valves

A trunnion mounted valve uses a ball supported by both a shaft and a post opposite the shaft and a seating arrangement using a floating seat. With a mechanically connected ball at the top and bottom pivot points, the process pressure pushes the upstream seat against the ball's sealing surface. 

Trunnion-mounted ball valve applications include pipeline, process, power, oil & gas, and other flow control applications where quality, design, safety, and environmental protection are paramount.

Tiger Valve Company (TVC) is a trunnion-mounted ball valve manufacturer.  

TVC Trunnion-Mounted Ball Valves (TMBV) meet the latest API, ISO, and ASME standards—manufactured using best-in-class materials and technologies. The result is the highest-quality and most competitively-priced trunnion-mounted ball valve available. 

All TVC TMBV address all of the safety, quality, and design issues important for ensuring consistent field performance and environmental protection. They provide superior performance in various applications, including oil, gas, and other liquids pipelines, tank farms, meter stations, chemical processing plants, and refineries.

Understanding Pigging and Pig Valves in Industrial Pipelines


Pigging is a method of introducing a mechanical device, commonly referred to as pigs or scrapers, inside a pipeline to perform various internal maintenance operations.The term PIG is said to be an acronym for "Pipeline Intervention Gadget". The process has been used for many years to scrub large diameter pipelines in the oil and gas industry. Today, the use of smaller diameter pigging systems is growing in many continuous and batch processing plants, as plant operators are looking for improved productivity and ways to reduce costs. 

Pig valves were successfully implemented into the oil and gas industry over five decades ago.  They are used extensively on oil and gas pipelines throughout Western Canada and the United States. They provide an efficient way to launch and retrieve pigs in the oil and gas industry, water treatment facilities, or anywhere critical pipelines need to be maintained.

Pigging is used to mechanically sweep and/or visually inspect inside of the pipeline. The pig or scraper is moved through the line by the differential pressure caused by the process fluid moving past at a higher velocity. The pig is inserted into what is known as a "pig launcher" (or launching station) which is a part of the pipeline with an oversized diameter to accomodate the installation of the pig. The launching station is then closed and the pressure driven flow in the pipeline is used to move the pig down the pipe until it reaches the receiving trap (the pig catcher or receiving station) where it can be removed. Pigs are used daily in the operation of pipelines for a variety of reasons, the most common are: pipe cleaning for improved line efficiency; locating flow obstructions; pipeline inspection; separating different products flowing through the pipeline; corrosion control; air purge; water removal; and flow volume validation.
