8500 Triple Offset

Technological innovation and design flair deliver high sealing performance.

Our 8500 Series Triple Offset range features patented ‘OCT’® sealing technology and maximised bore valve with high CV and truly circular geometry.

Available with a range of low-noise and anti-cavitation trims, the OCT-SW is specifically designed for seawater application with no graphite in contact with the line media whilst still maintaining firesafe certification.

Encompassing laminated, solid seal and hybrid polymer metallic seal designs, a multitude of sealing materials render it suitable for all applications.

A body-mounted seal reduces wear and graphite ‘washout’ that can affect other valves with a disc-mounted seal. And its torque seated design ensures consistent sealing performance.
