Ball valve / with trunnions - VB2, VB3
The Valbart VB2 and VB3 side-entry ball valve setup is made with a bi-directional sealant on the valve and uses two floating seats. The seats are designed to keep torque in check and will manage the valve without losing sealant power. This is made with zero differential pressure to keep the valve intact. These valves can also work well to seal off seats to make it easier for bleeding to occur in the entrapped cavity while the ball is in a closed position. This also works with a trunnion-mounted ball and an anti-blowout stem.
