Electric globe valve

Highlight: electric globe valve


Product introduction:


Actuator (or pneumatic actuator) and a globe valve. The difference lies in that the closing member is a valve disc, which rotates around the centerline of the valve body to achieve opening and closing. As the most widely used valve type, the electric globe valve (also known as electric stop valve) differs from the electric ball valve. Its popularity stems from advantages such as low friction between sealing surfaces during opening/closing, durability, small opening height, easy manufacturing, convenient maintenance, and applicability to both medium-low and high-pressure systems.
The closing principle of an electric globe valve is to rely on the electric thrust to rotate the valve stem, forcing the valve disc sealing surface to closely fit the valve seat sealing surface and block medium flow. It allows only unidirectional medium flow, requiring directional installation. Compared with gate valves, globe valves have longer structural lengths and higher fluid resistance, with less reliable sealing performance during long-term operation.

Product features:


  1. Simple structure, convenient for manufacturing and maintenance.
  2. Short working stroke and quick opening/closing time.
  3. Good sealing performance, low friction between sealing surfaces, and long service life.
  4. The structural forms of globe valve bodies include straight-through type, straight-flow type, and right-angle type. The straight-through type is the most common structure, but it has the highest fluid resistance. The straight-flow type has smaller fluid resistance and is mostly used for fluids containing solid particles or high viscosity. The right-angle valve body is mostly forged, suitable for globe valves with smaller nominal diameters and higher pressures.
  5. The friction force of the sealing surface during opening and closing is smaller than that of the gate valve, and it is wear-resistant.
  6. Usually with only one sealing surface, good manufacturing process and convenient for maintenance.
  7. The electric actuator is convenient for operation.
