The triple-offset butterfly valve is an industrial valve designed with a three-dimensional eccentric principle. Its triple eccentric structure (eccentricity between the stem and disc seal, stem and valve body, and disc seal cone and channel axis) enables metal-to-metal hard sealing with "zero friction" operation. Key advantages include:
- Leak-proof sealing: Achieves near-zero leakage through cam-effect torque sealing;
- Long service life: Friction-free operation, resistant to high temperatures (up to 425°C), high pressure (1.6-6.3MPa), and corrosive media;
- Low operating torque: Eccentric design reduces friction, easing operation;
- Precise control: Compatible with pneumatic/actuated systems for accurate flow regulation. Widely used in harsh conditions like petrochemicals and metallurgy.
