In this type of valve the sphere rests and spins on the seat ring,
transferring to these the stress it bears due to the action of the service pressures. The
insertion of resilient material to the seat ring assures a low torque operation as well as
a perfect seal. Our valves are submitted to various standards for fire testing, which
provides an effective metal to metal seal, in the event high temperatures destroy the
resilient material inserts in the seat rings. The design of our valves does not permit the
stem to be expelled due to the valve's inner pressure. The stem has a double Teflon seal,
of which the internal part is compressed against the seat of the body due to the inner
pressure effect of the valve, thus increasing the sealing action. The floating ball valve
can be manufactured with complete or reduced bore and can be operated with a lever or
mechanical, electromechanical, hydraulic and pneumatic operators. The variety of carbon
steels and alloys used allows us to supply appropriate valves for a wide range of
services.
