Convenient operation and control

Remote control capability: The electric actuator can receive remote control signals to achieve long-distance operation, which is convenient for centralized control in the control room, reducing the need for manual on-site operation, improving work efficiency and safety, and is especially suitable for some dangerous or difficult-to-reach working environments.

Simple and flexible operation: It can perform fast and accurate switch operations through electric control, and also retains the manual operation function. When the electric system fails or needs temporary debugging, the valve can be manually operated to ensure the normal operation of the system.

Compact and simple structure

Small size and light weight: Compared with some other types of valves, the electric stop valve has a relatively simple structure, occupies less space, is light in weight, and is easy to install and maintain, especially in places with limited space.

Parts are easy to process and assemble: Its structural design is simple, the number of parts is relatively small, and the manufacturing and assembly process is relatively easy, which reduces production costs and production cycles.

FAQ

1. How to judge whether the electric actuator of the electric actuated globe valve needs to be replaced?
When the electric actuator has the following situations, it may need to be replaced: First, the motor of the electric actuator frequently fails, such as overheating, burning, etc.; second, the output torque of the electric actuator decreases significantly and cannot drive the valve normally; third, the control accuracy of the electric actuator is seriously reduced and cannot meet the control requirements of the system; fourth, the mechanical parts of the electric actuator are seriously worn, deformed or damaged, resulting in the valve being unable to open and close normally.

2. How to solve the thermal expansion problem of the electric stop valve under high temperature and high pressure conditions?
Under high temperature and high pressure conditions, the valve body, valve stem and other components of the electric stop valve will change in size due to thermal expansion. In order to solve this problem, a certain expansion gap can be reserved during the design and installation of the valve, or a special expansion compensation device, such as a bellows compensator, can be used to absorb the size change caused by thermal expansion to ensure that the valve can work normally under high temperature and high pressure.

3. How is the compatibility of the control system of the electric actuated globe valve with other automation systems?
The control system of the electric stop valve can usually be connected to other automation systems through standard communication interfaces, such as Modbus, Profibus and other communication protocols. When selecting an electric stop valve, it is necessary to ensure that its control system is compatible with the communication protocol of other automation systems used on site in order to achieve system integration and automatic control. At the same time, the control system software also needs to have good compatibility and scalability to meet the personalized needs of different users.
