It is a high performance valve with a similar design to the double-eccentric metal seated valve in which the metal sealing ring is replaced by a PTFE ring. Therefore it´s a valve that can operate at high pressures while maintaining the sealing bidirectionally, with low torque and low friction between the seat and the disc that increase valve lifetime.

At the same time, the valve make the most of the characteristics of PTFE in terms of resistance to chemicals and solvents, high antiadhesivity and low coefficient of friction and toxicity while maintaining its properties at high temperatures properties.

This valve is particularly suitable for applications in chemical, petrochemical and pharmaceutical industries.
