the use of full bore
the Has the following advantages:
1, the use of FEP lining of the ball, with a high chemical
stability, can be applied in
addition: "molten alkali metals and
elemental fluorine", other than any strong corrosive properties;
2, the use of full bore,
floating ball structure, the pressure valve
can leak within the closed piping system easier to pass the ball
sweeping lines and
pipe maintenance;
3, the opening and closing piece ball and stem casting (forging) as a
whole, to prevent pressure changes due to
pressure caused by pieces of
the stem out the possibility of a fundamental guarantee for the
project in the use of safety;
4, compact structure, the smallest body cavity space, reducing the
retention of the medium, the other, a special molding process,
so that
good sealing surface density, coupled with the word combination of the
ring PTFE packing, the valve to achieve zero
leakage;
