The electric flange globe valve is composed of two parts: an electric actuator and a globe valve. The opening and closing parts of the electric flange globe valve are plug-shaped discs, and the sealing surface is flat or conical, and the discs are straight along the center line of the fluid. sports. The movement form of the valve stem includes a lifting rod type (the valve stem is raised and lowered, and the hand wheel does not rise), and there is also a lifting rotary rod type (the hand wheel and the valve stem rotate and rise together, and the nut is set on the valve body). Electric shut-off valve is only suitable for fully open and fully closed, adjustment and throttling are not allowed.

Features of Electric Flange Globe Valve
1. Compact structure, reasonable design, good valve rigidity, smooth passage and small flow resistance coefficient.
2. The sealing surface is made of stainless steel and hard alloy, which has a long service life.
3. Using flexible graphite packing, reliable sealing, light and flexible operation.
4. The driving mode is divided into manual, electric, pneumatic, gear transmission power, structure type: elastic wedge single gate, rigid wedge single gate and double gate.
5. It is widely used in petrochemical, thermal power plants and other oil and steam pipelines as opening and closing devices for connecting or cutting off the medium in the pipeline.
