I. Product Overview
The Electric Fully Enclosed Slide Gate Valve is specially designed for gas pipeline systems in iron and steel plants. It is mainly used for blast furnace gas, converter gas, coke oven gas, and other industrial gas systems for pipeline shut-off, system switching, and equipment isolation during maintenance.
1.1 Fully Enclosed Design
Considering the flammable, toxic, dusty, and complex operating conditions of blast furnace gas, the valve adopts a fully enclosed structure. The slide plate and main moving components are enclosed inside the valve body, helping reduce gas leakage during valve operation and improving the safety of both system operation and maintenance work.
1.2 Electric Operation and Automatic Control
The valve is equipped with an electric actuator and can be configured with open/close position feedback, remote operation, and interlock control according to project requirements.
It can also be integrated with the plant’s existing PLC or DCS control system, helping customers reduce manual field operation and improve the automation and centralized control of the gas pipeline system.
1.3 Customized for Actual Site Conditions
For new blast furnace projects, gas pipeline upgrades, or replacement of existing valves, the valve can be designed according to the customer’s actual pipeline diameter, operating pressure, gas temperature, installation space, flange dimensions, and control requirements.
This helps improve compatibility with existing pipeline systems, reduce field modification work, and simplify installation and commissioning.
II. Product Features
2.1 Fully Enclosed Structure for Improved Safety
The slide plate and switching area are enclosed within the valve body. During normal operation, the valve remains enclosed, making it suitable for toxic and flammable gas media such as blast furnace gas.
This design helps reduce the risk of gas escaping into the surrounding working area and improves operating safety.
2.2 Reliable Shut-Off for Maintenance Isolation
The valve is designed for the operating conditions of steel plant gas networks and can be used for isolation of gas mains, branch pipelines, and equipment connections.
When downstream equipment requires maintenance, process switching, or temporary shutdown, the valve provides reliable pipeline isolation and creates safer conditions for maintenance work.
2.3 Electric Drive for Higher Automation
The electric actuator allows local operation, remote control, open/close indication, and process interlocking.
By integrating the valve into the plant’s PLC or DCS system, customers can reduce manual operation in hazardous areas and improve overall system operating efficiency.
2.4 Suitable for Harsh Steel Plant Environments
The rigid box-type enclosed valve body provides good mechanical protection for internal moving parts and helps reduce the influence of dust and external environmental conditions.
The valve is suitable for continuous-duty applications in steelmaking, ironmaking, metallurgy, and industrial gas handling systems.
2.5 Customized Design for Special Applications
For large-diameter pipelines, elevated temperatures, special pressure requirements, limited installation space, or existing pipeline renovation projects, the valve structure can be customized.
Valve body dimensions, sealing arrangement, actuator configuration, connection dimensions, and electrical control options can all be adapted to the actual project conditions.
III. Applications
3.1 Blast Furnace Gas Systems
The valve can be installed in blast furnace gas mains, branch pipelines, gas purification systems, and related process pipelines where reliable shut-off and isolation are required.
3.2 Converter Gas and Coke Oven Gas Systems
It can also be applied to converter gas and coke oven gas systems for pipeline isolation, equipment protection, maintenance shutdown, and process switching.
3.3 Gas Recovery and Distribution Systems
The valve is suitable for gas recovery, gas distribution, gas cleaning, and other industrial gas handling systems in steel plants.
Typical installation positions include gas pipelines before and after fans, dust collectors, purification equipment, and other process units.
IV. Product Structure
4.1 Main Components
The Electric Fully Enclosed Slide Gate Valve mainly consists of:
- Valve body
- Slide plate assembly
- Sealing system
- Electric actuator
- Transmission mechanism
