Rubber seated Butterfly Valves for
High Pressure Applications
New cosine-curve seat
The new cosine-curve seat (patent pending) allows better
performance in reducing friction, torque and wear than the
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.
