High-performance ball valve V-rings
What is a Ball Valve V-Ring?
The ball valve V-ring (V-Packing Ring) is the core sealing component of ball valves. It adopts a V-section design and adapts to the sealing surface through preload. It is widely used in petroleum, chemical, energy, and other high-pressure and high-temperature working conditions. Its unique structure can effectively prevent media leakage and improve the valve's service life.

Why Choose Our Ball Valve V-Rings?
Excellent material properties
Multiple material options are available: NBR (nitrile rubber), FKM (fluoroelastomer), EPDM (ethylene propylene diene monomer), and other materials suitable for extreme environments from -40°C to 250°C.
Chemical Resistance: Resistant to oils, acids, alkalis, and organic solvents, extending equipment maintenance intervals.
Precision process guarantee
High-precision mold forming: the tolerance is controlled at ±0.05mm to ensure a perfect fit with the ball valve and eliminate leakage.
Elastic optimization design: the dynamic sealing pressure is up to 50MPa, which is suitable for frequent opening and closing.
Customized solutions
Support non-standard size customization (ISO 3601/DIN 3771 standard), provide technical drawing review services, and quickly respond to customer needs.
Coverage of user pain points: Downtime due to seal failure, high cost of frequent replacement, and difficulty in matching special working conditions
Application Scenario (H2)
Oil and gas pipelines: high pressure resistance, hydrogen sulfide corrosion resistance, to ensure the safety of transportation.
Chemical equipment: Resists strong acid and alkali media, reducing maintenance frequency.
Water treatment system: EPDM material is anti-aging and suitable for long-term immersion environments.
