Inverted Pressure Balanced Plug Valves
Designed specifically for extreme operating pressures up to Class 2500, TSV inverted pressure balanced plug valves utilize internal dynamic equalization ports connecting the upper and lower plug chambers. This balances line pressure across the plug taper, eliminating thermal binding and drastically reducing actuation torque.

Inverted Pressure Balanced Dynamic Architecture
How dynamic pressure balancing eliminates taper wedging and drastically reduces operational torque in Class 2500 services.
Dynamic Chamber Pressure Equalization
Equalization channels drilled through the inverted plug transmit line pressure directly to the plug chamber, equalizing axial forces.
Elimination of Taper Wedging
Unlike conventional upright plugs that jam under pressure, the inverted design utilizes pressure differentials to maintain balanced seat contact.
Anti-Blowout Stem Retention
The valve stem is mechanically retained within the body bonnet structure, fully isolating it from internal chamber thrust loads.
Drastic Actuation Torque Reduction
Lower operating friction enables smaller actuators, reducing skid footprint, weight, and automated valve power consumption.
