The principle and application of pneumatic cut-off ball valves in industrial systems

The core of the pneumatic cut-off ball valve is to drive the actuator through compressed air, enabling the valve to quickly open or close to cut off or conduct the medium. I. Core Working Principle The pneumatic cut-off ball valve is mainly composed of an **air-driven actuator** and a **ball valve body**. Its working process can be divided into 3 steps: 1. Signal Reception: The control system (such as PLC, DCS) sends on/off signals to control the on and off of compressed air.

What is the difference between electric valves and pneumatic valves?

Electric valves and pneumatic valves differ in terms of power source, control performance, applicable scenarios, and maintenance costs, as follows: 1. Source of Power Electric Valve: It uses an electric motor as the power source and is driven to open or close the valve by the motor. The electric motor typically uses mains electricity or other direct current power sources. As long as there is a stable power supply, the electric valve can operate normally.

When choosing an air actuator, what factors should be taken into consideration?

When selecting pneumatic actuators, the following key factors need to be comprehensively considered to ensure a perfect match with the actual application scenarios and achieve efficient and reliable control objectives: I. Basic Performance Parameters 1. Torque/Thrust Requirements Calculate the required torque based on the type and size of the valve (such as ball valve, butterfly valve, gate valve), and ensure that the output torque of the actuator is

The differences between pneumatic shut-off valves and electric shut-off valves

Pneumatic shut-off valves and electric shut-off valves are two common types of valves used in industrial automation control systems. They differ significantly in terms of driving methods, response speed, application scenarios, and maintenance requirements. Here are the main differences between them: --- ### 1. Driving Method - **Pneumatic Shut-off Valve**: Powered by compressed air, it operates the valve's opening and closing through a cylinder or pneumatic actuator.
