Soft Seated Trunnion Ball Valve

Soft Seated Trunnion Ball Valve

Chaoda’s soft seated trunnion ball valve is engineered for precision flow control and reliable isolation in larger sized, high-pressure applications. With a trunnion-supported ball and pressure-assisted soft seats, it offers smooth operation, reduced torque, and tight shut-off performance. The valve’s robust construction, versatile seat materials, and advanced sealing features, including Double Block & Bleed and Double Piston Effect options, make it an ideal solution for applications requiring high integrity and low maintenance.

Body provides structural integrity

Precision machined ball maximizes sealing surface for reliable isolation

Machined seat rings with soft insert for optimal sealing capability

Body and trunnion seal maintain ball support during operation

Seat spring consistently provide loading forces to keep the ball in contact with the seat interface

High-strength stem as standard to ensure operational safety. Trunnion bushing helps ensure consistent operating torque

Low Fugitive Emission packing available

Live-loaded gland using Belleville Spring washers applies pressure loading to the packing to prevent leaking caused by thermal cycling or packing wear

ISO mounting for standardized actuation mounting
