Analysis of Electric Gate Valve Technology
1. Basic definitions and types
Electric gate valve is an industrial valve that is driven by an electric actuator to open and close the gate, mainly used for cutting off or flow control of pipeline media. According to the driving method, it can be divided into:
Straight stroke electric gate valve: The gate moves vertically and is suitable for high-pressure large-diameter pipelines.
Angular stroke electric gate valve: The gate rotates 90 ° to open and close, with a compact structure, suitable for space limited scenarios.
2. Core parameters
Typical parameter values
Diameter range DN25~DN1000 (can be even larger for special customization)
Pressure rating PN1.6~42.0MPa (conventional PN1.6~15.0MPa)
Applicable temperature -40 ℃~+250 ℃ (divided into normal temperature/high temperature/low temperature types)
Sealing form: hard seal (metal to metal) or soft seal (rubber)
Drive mode: electric (AC220V/380V), dual-purpose flashlight
3. Performance characteristics
Full bore design: low flow resistance, high flow capacity, suitable for media containing particles.
Self cleaning function: The sealing surface of the gate can scrape off adhesive materials, reducing maintenance frequency.
Explosion proof option: Some models support ExdIIBT4 explosion-proof certification and are used in flammable and explosive environments.
4. Typical application scenarios
Water conservancy engineering: reservoir inlet and drainage system interception.
Metallurgical industry: Control of blast furnace gas and dust removal pipelines.
Chemical industry: Corrosive media (requiring lining with fluorine or alloy materials).
5. Selection suggestions
Material selection:
Corrosive medium: 316L stainless steel or fluorine lined valve body.
High temperature environment: Use chromium molybdenum steel or high-temperature alloy sealing surface.
Executor configuration:
When frequent flow adjustment is required, priority should be given to intelligent models with 4-20mA signal input.
