Overview

High temperature pneumatic ball valve is an advanced control valve with a right angle rotary structure. The V-shaped ball valve does not require repair for a long time and has a long service life, providing you with a truly efficient valve for controlling process conditions. Suitable for various control scenarios, with advantages such as compact structure, small volume, and the ability to be installed in a compact position

Product Details

High temperature pneumatic ball valveIt is an advanced control valve with a right angle rotary structure, which is used in conjunction with a valve positioner to achieve proportional adjustment; Used in conjunction with a two position five way solenoid valve and control box, it can achieve switch control. The V-shaped ball valve core is designed with a specially shaped V-shaped notch, which has precise flow characteristics and control functions, suitable for various control occasions, compact structure, small volume, and can be installed tightly. Suitable for controlling gas, liquid, and solid granular media. Due to the seamless rotation between the valve core and valve seat, it has great shear force and self-cleaning performance, especially suitable for controlling suspensions and solid particles containing fibers or small solid particles. Therefore, this product can be widely used in the self-control systems of industrial sectors such as petroleum, chemical, papermaking, chemical fiber, power, metallurgy, pharmaceuticals, and environmental protection.

Product Features

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 to maintain, pneumatic ball valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement relatively convenient.

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. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.

8. Because the power source of pneumatic ball valves is gas, usually at a pressure of 0.2-0.8MPa, it is relatively safe. If a pneumatic ball valve leaks, compared to hydraulic or electric valves, the gas can be directly discharged without polluting the environment, and it has higher safety.

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

High temperature pneumatic ball valve

actuator

Adopting a new series of GT type pneumatic actuators, with double acting and single acting (spring reset), gear rack transmission, safe and reliable; The large-diameter valve adopts a series of AW type pneumatic actuator fork type transmission, with a reasonable structure and large output torque, and is available in double acting and single acting types.
1. Gear type dual piston, with large output torque and small volume.
2. The cylinder is made of aluminum material, which is lightweight and aesthetically pleasing.
3. Manual operating mechanisms can be installed at the top and bottom.
4. The rack and pinion connection can adjust the opening angle and rated flow rate.
5. The actuator can be equipped with live signal feedback indicators and various accessories to achieve automated operation.
6. The IS05211 standard connection provides convenience for the installation and replacement of products.
7. The adjustable screws at both ends provide a ± 4 ° adjustable range for standard products between 0 ° and 90 °. Ensure synchronization accuracy with the valve.
