Ball Valve

The floating ball design of Ball Valves is the universal choice for most process and utility applications. In this design, sealing takes place by allowing the ball under pressure to move towards the downstream seat to ef fect a tight seal. Other designs, such as the Trunnion Mounted design, are also maunfactured.
       
  ANTISTATIC FEATURE : Build-up of static electricit y can occur as a result of constant rubbing of the ball against the PTFE seats. This can be a potential fire hazard, especially while handling inflammable fluids. To provide electrical continuit y, spring-loaded plungers are provided between the stem and the ball in single-piece and two-piece reduced bore (80mm and above) and full bore (40mm and above) valves. For smaller sizes, this is achieved through 35% Carbon-filled PTFE stem seals. Depending on the choice of seals, the designs also provide for additional spring-loaded plungers between the stem and the body for full mechanical antistatic capability.
