Pneumatic ball valve consists of valve body, valve core and valve seat, valve core and valve seat moving and cohesion, products of the body is equipped with the cylinder, the cylinder of the hydraulic cylinder of flip moving and cohesion, migration, and seat after cylinder to manipulate the gate of the power switch, then make it more simple, and the fitness of ball valve manufacturer cylinder has hand can after appearance of relay or a valve to its manipulation, can then be long button to carry out the manipulation of gate valve, then more convenient.
Just want to use pneumatic ball valve pneumatic execution rotate 90 degrees for pneumatic valve operation method and small flip torque can be closed. Completely equivalent body wall for the media to the small friction resistance, direct flow. It is generally believed gate right immediately do open/close the application. Gate itself is the main characteristics of compact structure, easy to use and maintenance, use strong electrolyte, organic solvents, acids and general work materials such as gas, but also for the working environment of extreme substances, such as O2, hydrogen peroxide, methane and PVC, etc. Gate valve can be overall, also can be a combination.
In modern automatic control technology, pneumatic ball valve is used very popular a kind of pneumatic actuators. According to the pneumatic actuator, manipulate data signal driving ball valve power switch position, to control or adjust the control of the medium inside the pipeline button. The pneumatic ball valve selection must pay attention to? Below we're going to tell 14 needle valve everyone about the pneumatic ball valve selection of key points.
1. The application of medium. Must consider the characteristics of the medium of many acid medium corrosion. AoTuGan, very easy to damage the surface, how to solve? Can use the corrosion resistance of the lining fluorine material, do wear resistance, it has pneumatic rubber fluorine ball valve, etc.
2. The application materials. Circuit board materials able to selection on the basis of field work condition, generally have a ductile casting, stainless steel plate, steel, carbon steel, plastic, etc., according to the demand of the higher quality also have environmental health level of pneumatic ball valve, the material better.
3. The application of work pressure. Meaning is refers to the pressure, can be divided into low voltage, the natural pressure, high pressure, high pressure, 1.6 MPa belongs to the commonly used working pressure, natural refer to 38 needle valve it as the selection of data information.
4. The application of temperature. High temperature can be divided into pneumatic ball valve, pneumatic ball valve, cryogenic medium temperature and room temperature pneumatic ball valve pneumatic ball valve.
5. Application security channel. It can be divided into three links and grant instruction pneumatic ball valves, pneumatic ball valve in accordance with the characteristics of the ball valves will be divided into the fluctuation ball valve and fixed ball valve which, in a nutshell is not the same selection are selected according to specific working conditions.
