Electric high-pressure gate valve

Electric high-pressure gate valve

Electric highpressure gate valve is a valve driven by an electric actuator, used to control the on/off of the medium in high-pressure pipeline systems. Here is a detailed introduction:

Structure and working principle: usually composed of valve body, valve cover, valve stem, gate, electric actuator, etc. The motor in the electric actuator drives the gearbox, which in turn drives the valve stem, causing the gate to move up and down along the valve seat guide rail, achieving the opening or closing of the valve.

Technical parameters: nominal pressure can reach PN16.0MPa, American standard ANSI 600LB, etc; The nominal diameter is generally between DN50-DN600mm; The common power supply voltages are 380V/50Hz, 220V/50Hz, etc; The protection level is generally IP55, and IP67 can be customized.

Product features: Good sealing performance, using pressure self tightening sealing or gasket sealing structure, and the sealing surface is often welded with hard alloy. The fluid resistance is low, and after the gate is opened, the medium can pass through without obstruction. It can achieve remote control and automated operation, and the electric actuator has fast response and precise control.

• Connection method: There are mainly two types: flange connection and welding connection. Flange connection is easy to install and disassemble, while welding connection is suitable for high-pressure, high-temperature and other occasions that require extremely high sealing performance.

Application areas: Widely used in high-pressure pipeline systems in industries such as petroleum, chemical, power, and natural gas, for cutting off or regulating the flow of media such as water, steam, oil, and natural gas.
