Soft seated Butterfly Valve - Sealing, Performance, and Durability

Flowrates butterfly valves are designed to ensure absolute sealing and enhanced resistance, making them ideal for the most demanding industrial and marine environments. Thanks to their high-precision vulcanized lining, they provide comprehensive corrosion protection, extended lifespan, and maximum reliability, even under full pressure at end-of-line service.

Vulcanized Lining Technology – Zero Leakage, Zero Compromise

✅ 100% sealing on upper and lower shaft joints, achieved through a dual primary and secondary seal system.

✅ Vulcanized lining molded under 150-bar pressure, ensuring perfect adhesion and extreme durability.

✅ Full corrosion protection: The lining completely covers the valve body interior, preventing any interaction between the fluid and the valve material.

✅ No need for additional flange gaskets, as the lining extends beyond the flange faces, simplifying installation and improving sealing.

✅ Suitable for vacuum applications and high-velocity fluids: The lining is permanently fixed, preventing any deformation or aspiration into the pipeline.

Maximum Reliability and Performance

✔ Zero deformation, zero lining detachment, even in extreme conditions.

✔ Minimal seat wear, extending service life up to 3 times compared to replaceable linings.

✔ Low torque operation, thanks to an optimized design that facilitates automation and reduces mechanical stress.

✔ Permanent dry shaft lubrication, ensuring extended component lifespan and smooth operation.

✔ Bidirectional flow stability, providing efficient and homogeneous fluid regulation.
