Rising Stem Ball Valve

● Friction-Free Operation: The ball turns only after moving away from the seat, eliminating friction and reducing wear common in traditional ball, gate, and plug valves.

● Injectable Packing: Allows for online maintenance by injecting packing into the stem through a port, effectively controlling emissions. This feature is applicable to all models with a 

sealed cover.

● Single Seat Design: The rising stem ball valve's single static seat ensures zero downstream leakage and avoids the pressure 

build-up issues common with double-seated designs.

● Extended Service Life: This valve can replace other valves prone to sealing failures, such as standard ball valves, gate valves, and plug valves, reducing failure rates and maintenance costs significantly.

● Optimal Flow Characteristics: Both full-bore and reduced-bore valves maintain high Cv values when open, enhancing pump efficiency and minimizing corrosion issues.

● Top Entry Design: Facilitates inline inspection and maintenance after decompressing the pipeline system, simplifying upkeep.

● Dual Stem Guides: The stem moves smoothly up and down, and rotates along guide pins, ensuring stable control.

● Self-Cleaning Feature: When the core is off the seat, the medium flows 360 degrees along the sealing surface, washing away impurities.

● Low Torque Operation: The elimination of sealing friction makes the valve easy to turn, allowing the use of a small handwheel without the need for a gearbox, except in very large 

sizes.

● Wear-Resistant Hard Sealed Surfaces: The core's sealing surfaces are overlayed with hard alloy and polished, maintaining seal 

integrity even under harsh conditions.

● Mechanical Wedge Seal: The inclined surface at the bottom of the stem provides a mechanical wedge force, ensuring continuous 

tight contact between the core and the seat.
