ANSI Standard Stainless Steel CF8, CF8M Flanged Float Type Ball
Valve
Product introduction:
A Ball Valve is a shut-off valve that rotates a ball with a bore
inside it to permit, restrict, and control the flow of liquids,
gases, and vapors in a pipe system. The shaft that connects the
ball to the operational and controlling mechanism that rotates the
ball is mounted against two seats. The fluid is not allowed to pass
through the valve when the cross-section of the bore is
perpendicular to the area of the flow. The area of the bore that is
exposed to the floor determines how much fluid flows through the
valve and at what pace.
Float ball valve is the superior product developed upon advanced
technology home and abroad, provided with updated design general
industrial standard, Switch indication of hand operated float ball
valve, with valve locking device, anti-static device, fire
protection structure, and middle flange leak-tight structure, with
dependable sealing and self-relieving function.
They can be turned manually, with the aid of an actuator, a wrench,
or a lever that is manually turned by the operator. To open or
close the valve, torque is exerted to move the lever arm by 90
degrees in either a clockwise or counterclockwise direction. The
valve is open if the lever arm is perpendicular to the pipe. A
closed valve is indicated by the lever arm being perpendicular to
the pipe. To meet varied industrial applications, it is available
in a variety of designs and characteristics. Depending on the
industry in which this valve is used, different norms and
specifications apply.

Product features:
1. Small hydraulic resistance, and its resistance coefficient is
the same as the tube of same length;
2. Simple structure, small and light;
3. Compact and reliable, sound sealing performance for plastic is
widely used for sealing surface of the ball valve contributing to
the large-scale application to vacuum system.;
4. Easy to operate, fast opening and closing for it can be switched
from fully opened to closed by only rotating 90 degrees and easy to
be controlled from long distance;
5. Easy to maintain, and simple ball valve structure. Sealing ring
is mostly movable to facilitate convenient removal and replacement;
6. When it is fully opened or closed, the ball valve and the
sealing surface of valve seat are separated from medium , thus the
medium will not lead to corrosion of the sealing surface of valve
when passing through;
7. Wide application sphere, its diameter varies from several
millimeters to few meters, and it can be applied under high vacuum
conditions or high pressure.
