As valve sizes and operating pressures increase, however, several factors need to be considered if that valve is opening with little or no pressure downstream.
When a ball valve is closed, product is trapped in the cavity of the ball. If that product offgasses, it will build up pressure in the cavity area which could lead to a failure or other hazardous condition. A vented ball is a ball that has been factory drilled on one side to relieve the potential for pressure build up in the ball .
