DBB ball valves have SPE seats to the upstream and also the downstream aspect. SPE seats will provide a seal in one path only. Consider the case once the valve is entirely shut, The one piston outcome with the upstream side essentially pushes the valve seat in opposition to the ball to supply the seal. In the situation of seat have on or seat leaka… Read More
