Overview

Q641F pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast, with a fast opening and closing speed of 0.05 seconds per time, so it is usually called a pneumatic quick cut-off ball valve. Usually, various accessories are configured, such as solenoid valves, air source processing triplets, limit switches, locators, control boxes, etc., to achieve local control and remote centralized control. The opening and closing of valves can be controlled in the control room without the need to manually control them on site or in high-altitude or dangerous areas, which greatly saves human resources, time, and safety.

Product Details

　　Q641F Pneumatic Ball Valve

Only the operation of rotating the pneumatic actuator 90 degrees with the air source and a small rotational torque is needed to close it tightly. The equal inner cavity of the valve body provides a low resistance and straight passage for the medium. It is generally believed that ball valves are suitable for direct opening and closing use. The main characteristics of ball valves are their compact structure, easy operation and maintenance, suitable for general working media such as water, solvents, acids, and natural gas, as well as for media with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. The valve body of a ball valve can be integral or modular.

The working principle is to rotate the valve core to make the valve unobstructed or blocked. The switch is lightweight, small in size, can be made into a large diameter, reliable in sealing, simple in structure, easy to maintain, and the sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium. It has been widely used in various industries.

A type of valve that belongs to the same category as a plug valve, except that its closing element is a sphere that rotates around the centerline of the valve body to achieve opening and closing.

It is mainly used in pipelines for fast cutting speed, distribution, and changing the flow direction of media. It is a new type of valve that 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 ball valves is widely made of plastic, with good sealing performance, and has also been widely used in vacuum systems.

4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.

5. Easy maintenance, simple structure, and generally movable sealing rings make disassembly and replacement relatively convenient.

6. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.

7. Widely applicable, with diameters ranging from a few millimeters to several meters, suitable for applications from high vacuum to high pressure.

8. Because the power source uses gas, usually at a pressure of 0.2-0.8MPa, it is relatively safe. If there is a gas leak, compared to hydraulic and electric systems, the gas can be directly discharged without polluting the environment, while also having higher safety.

9. Compared to manual and turbine rotating ball valves, it can be configured with larger diameters. (Manual and turbine rotating ball valves are generally below DN300 diameter and can reach DN1200 diameter.)
