The use of chlorine-specific safety ball valve

Chlorine ball valve
and plug valve of the same class, the difference is ball is a sphere
with a circular through also for the opening and closing parts, ball
valve
with the stem around the center line of rotation to achieve the
valve opening and closing Purposes.
Basic series of liquid chlorine Q41F46 ball valve type, can be
divided on points (two) two-and three-piece ball and have a general
structure with the fluid resistance of the small, open and close fast,
simple structure, 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;
5, two-piece, three-piece structure can adapt to different
requirements of the pipeline system and working conditions, including
three ball to allow separation of the main body and both sides of the
body can achieve fast online replacement and maintenance.
Ball valve has an exceptionally strong chlorine corrosion resistance, suitable
temperature conditions in the -20-150 ℃, long-term transport any
concentration of acid, alkali, salt liquid medium. Long service life,
aging, toxin-free advantages of both the strength of carbon steel shell,
but also corrosion-resistant materials in lined, oil, chemicals,
rubber, plastics, pharmaceuticals, paper making, electroplating,
metallurgy, etc. Ideal for many industries. Scope: Urban, chemical,
metallurgy, petroleum, pharmaceutical, food, beverage, environmental
protection.
