The double offset (double eccentric) disc structure of the TOMOE High Performance 300 Series creates a smooth camshaft effect. This allows for full control of the rotational axis between 10 and 90 degrees and provides a solid seal in many applications.

These valves are coated with Metal-Metal or RPTFE-Carbon Graphite for seat sealing at high operating pressure and high operating temperature. The sealing levels of the valve seals can reach from ISO Leakage 5208 Rate C to ISO 5208 Rate A zero sealing.

These 300 Series Metal-Metal valves also have Fire Safe certificates.
