New cosine-curve seat The new cosine-curve seat (patent pending) allows better performance in reducing friction, torque and wear than the previous design. Much longer life with spherical design Similar to a spherical body rotating inside a spherical area, the operation of the disc is smooth and unhindered. Torque is reduced and the valve life is lengthened. Self-aligning stem seal through backup ring The stem seal is the primary and secondary seal system. The backup ring functions as the self-aligning stem seal. Ease of maintenance The field replaceable seat ring makes maintenance easy and reduces maintenance costs.
