Product Description

Product advantage

Q11F two-piece ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Ball valve is a new type of valve widely used in recent years, it has the following advantages:
1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.
2. Simple structure, small size and light weight.
3. Tight and reliable, the sealing surface material of the ball valve is widely used in plastic, good sealing, and has been widely used in the vacuum system.
4. Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 degrees, easy to remote control.
5. Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
6. When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause the erosion of the sealing surface of the valve.
7. Wide range of application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, it should all be spherical at the inlet and outlet, thus cutting off the flow.

Matters needing attention

Q11F two-piece ball valve can be divided into straight-through type, three-way type and right-angle type according to its channel position. The latter two ball valves are used for distributing media and changing the flow direction of the medium. Two piece ball valve installation and maintenance should pay attention to the following matters:
1. Leave the position for the valve handle to rotate.
2. Cannot be used as throttling.
3 Ball valves with transmission mechanisms should be installed upright.

Working principle

The working principle of the Q11F two-piece ball valve is to make the valve open or blocked by rotating the valve. Ball valve switch light, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and sphere are often in a closed state, not easy to be washed by the medium, in various industries have been widely used.
A. Start the process
B) The closing process
4 For the last few turns of the handwheel rotation, the angular plane at the bottom of the stem mechanically wedges towards the compression sphere so that it presses tightly against the seat to achieve a complete seal.
