Specification of Trunnion Ball Valve Stainless Steel
Ball Valve is used primarily for On-Off Service. Ball Valve is less satisfactory used for service throttling. Ball Valve is fast workmanship, easy maintenance, do not need to be lubricated with oil.
Ball Valves are not restricted to certain fluid materials. They are used for: steam, water, oil, gas, air, corrosive fluids, slurry (coarse particles) and dry powder materials.
The main elements of Ball Valve structure are body, seat, ball. There are two main types of Ball Valve
1). Top Entry: ball and seat mounted through the top.
2). Split body: ball and seat mounted at the end.
Ball Valve is produced in a wide range of materials: cast iron, malleable iron, bronze, aluminum, carbon steel, stainless steel, brass, titanium, zirconium, tantalum and some mixtures of corrosion and plastic resistant materials. has been available several decades ago, this valve is widely found and widely used in the chemical industry since several decades ago.
Ball Valve is basically an adaptation of the Valve Plug. Instead of a stopper, the Ball Valve has a ball with a hole through one side connecting the entrance and exit and the body. On the open position, while turning the ball 90˚ resulted in closed. In the guarantee to prevent leakage from the outside, Ball Valve employs tank guarantee from ring to conventional packing. The guarantee on the final connection will follow the pipeline specifications and is identical to the warranty used for the incorporation of other pipes and discharges. Ball Valve offers On-Off swivel operation that is fast, easy to maintain, does not require lubrication, and provides guarantees related to obligatory relationships. These valves are limited in usage due to the nature of the position and the resistance material to pressure and temperature. Although lubricants are not important, some Ball Valves design a combination of side door lubricants and outdoor lubricants. Where closing is important, and Valve's period of detention is not possible, lubricant properties will ensure the ability to generate collateral on abrupt conditions.
