electric gate valve

The electric gate valve DN250 has a complete range of materials, which can be reasonably selected according to actual working conditions or user requirements. It can be applied to various pressure, temperature, and medium conditions, including water, steam, oil, acid, strong oxidizing media, urea, and other media.

1、 Structural characteristics

It usually consists of an electric actuator in the upper part and a valve in the lower part. It has a compact structure, reasonable design, good valve rigidity, channel flow, and low flow resistance coefficient. The sealing surface is made of stainless steel and hard alloy, with a long service life. In addition, it also uses flexible graphite packing board, which is reliable in sealing and easy to operate.

2、 Functional Features

It has multiple functional features, including full Chinese display, automatic phase sequence correction, phase loss protection, control mode (supporting 4-20mA analog signal control and feedback), prohibition delay protection, electronic interlock protection, instantaneous over torque protection, etc. These features make electric gate valves more convenient and safe to operate and maintain.

Materials and Applicable Media

The valve body material variety is complete and can be reasonably selected according to actual working conditions or user requirements. It can be applied to various pressure, temperature, and medium conditions, including water, steam, oil, acid, strong oxidizing media, urea, and other media.

3、 Installation and maintenance

During installation and maintenanceElectric gate valve DN250When doing so, it is important to pay attention to the following points:

Bypass device: It is recommended to add a bypass device between the upstream and downstream of important high-pressure large-diameter valves to reduce the opening and closing pressure difference, alleviate the abrasion of the sealing surface by the gate plate at the moment of opening and closing, and also help reduce the electrical torque and manufacturing cost.

Pipeline flushing: Pipeline flushing is carried out to prevent debris inside the pipeline (such as iron filings, welding slag, welding rod heads, nuts, etc.) from damaging the sealing surface.

Installation direction: It is recommended to install the gate valve stem vertically upwards. Tilting installation will increase the chance of the gate getting stuck. When installing horizontally, there should be installation brackets to support the electrical installation, and the valve stem should be calibrated during installation.

Professional operation: When installing and debugging electric gate valves, professional personnel should carefully follow the requirements.

4、 Application scenarios

Suitable for cutting off or connecting media in pipelines in current control, remote control, explosive environments, and situations that are not easy to manually operate. It has a wide range of application scenarios, not only suitable for conventional industries such as petroleum and chemical, but also for special explosive situations.
