The QuadroSphere® Ball Valve from Val-Matic Valve & Manufacturing Corporation is a forged-steel, trunnion-mounted ball valve that is designed to serve a variety of applications where typical trunnion ball valves often experience problems.
Val-Matic's QuadroSphere features a unique contoured ball with four recessed surfaces, allowing solids to be flushed from the body/ball cavity to prevent them from being trapped around the back of the seat rings and bearings.
Recessed surfaces on the ball provide lipped edges for scraping the seats clean to avoid buildup of solids and scale. Seating surfaces are out of the flow path and fully protected from direct flow. Special machining of the ball substantially reduces the ball-to-seat surface contact, creating less resistance during cycles and lowering the operating torque.
The QuadroSphere maintains a fraction of the resistance across the seating surfaces when cycling, reducing wear up to 70 percent and improving the performance life of the ball and seats. With its unique contoured ball design, the valve solves difficult application problems in industries such as oil and gas production and pipelines, refining, geothermal, power, chemical, pulp and paper, cryogenic, and mining/steel.
The self-flushing feature makes the QuadroSphere stand out in these industries where the media flowing through the valve has a tendency to collect and solidify, causing other valves to fail. Further, it comes standard as fire-safe for flammable materials such as natural gas, oxygen, gasoline, and oil.
The QuadroSphere is available in sizes 2 NPS and larger in pressure classes of 150 to 2500 with a variety of body, seat and seal materials to meet specific application needs. It is also designed in accordance with API 6D and ASME B16.34 requirements, carries the API 6D Monogram, and has been certified to API 607, Fire Test standard.
Val-Matic's QuadroSphere Ball Valve meets standards API, ASME/ANSI, BS, ISO, MSS, and NACE and is also available with pneumatic, electric, gear, or level actuation.
