Why Choose a Circular Groove Design?
Improve Sealing Reliability in Contaminated Media
The circular groove creates additional space around the sealing area, helping reduce the accumulation of particles, wax, slurry, or process deposits that may affect sealing performance during repeated valve operation.
This design is commonly selected for applications where process media are prone to contamination or build-up.
Support Emergency Sealant Injection
For valve designs equipped with sealant injection systems, the circular groove can work together with the valve structure to create an additional sealing chamber.
This design is commonly specified for:
Natural Gas Pipelines
Sour Gas Service
Fugitive Emission Control
Emergency Valve Maintenance
Project-specific sealing configurations can be customized according to customer drawings.
Reduce Initial Operating Resistance
Compared with a completely flat sealing surface, the circular groove design can optimize the contact area between the ball and valve seats.
For valve manufacturers, this design may contribute to:
Smoother valve operation
Improved actuator matching
Reduced operating resistance during opening and closing
More stable torque characteristics throughout the valve service life
Actual operating performance depends on valve design, seat material, and application conditions.
Full Bore Design for Unrestricted Flow
The straight-through full-port bore allows process media to pass through without intentional flow restriction.
Typical benefits include:
Reduced pressure loss
Improved flow efficiency
Suitable for pipeline pigging systems
Reduced risk of material accumulation inside the valve
This design is commonly specified for transmission pipelines and process systems requiring full-bore flow.
Stable Performance Under High Differential Pressure
Unlike floating ball valves, the trunnion-mounted structure supports the ball from both the upper and lower shafts.
This design helps maintain stable positioning of the ball under higher operating pressures and is widely used in larger valve sizes and demanding industrial applications.
