The handleless valve is a device that realizes the switching operation of the valve through external force or medium pressure. Compared with the traditional manual valve, the handleless valve is more flexible, convenient and intelligent. This article will introduce in detail the principle, scope of application of handleless valves and its comparison with traditional manual valves.

The principle of handleless valves is mainly based on the control of electronic instruments and actuators, and the valve is opened and closed through electronic signals or medium pressure. Its essence is to drive the actuator through external control signals, thereby changing the opening and closing degree of the valve. Handleless valves have the advantage of automated control, enabling remote operation and program-controlled equipment, improving equipment automation and production efficiency.

Handleless valves have a wide range of applications and can be found in many industrial areas. For example, it is widely used in chemical industry, petroleum, natural gas, electric power, food, pharmaceutical, water treatment and other fields. Handleless valves can cope with various harsh working conditions such as high temperature, high pressure, and corrosive media, ensuring safe and reliable operation of the equipment.

Handleless valves offer many advantages over traditional manual valves. First of all, the operation of the handleless valve is more convenient and does not require manual direct touch operation, which reduces the complexity and labor intensity of manual operation. Secondly, handleless valves can be remotely controlled through electronic instruments and are suitable for automated program-controlled equipment, improving the automation and production efficiency of the equipment. In addition, the handleless valve can also realize remote monitoring and real-time alarm through the monitoring system, and promptly handle equipment failures and abnormal situations.

The development of handleless valves also faces some challenges and limitations. First of all, the installation and maintenance costs of handleless valves are relatively high. They rely on the support of electronic instruments and actuators and other equipment, and require regular inspection and maintenance. Secondly, the control system of handleless valves is complex and requires professionals for debugging and maintenance. In addition, the reliability and safety of handleless valves is also an important issue and needs to be guaranteed through strict design and testing.

To sum up, the handleless valve, as a new type of valve device, has wide application prospects and huge development potential. With the development of information technology and the continuous improvement of automated control, handleless valves will be more widely used in various industries. The development and research of handleless valves are of great significance for improving the automation of equipment, reducing labor intensity and improving production efficiency.
