Electro-hydraulic Slide Gate Valve

Factory supply electro-hydraulic slide gate valve for silo and coal drop pipe cut-off control. Integrated electro-hydraulic driving, stable operation, zero dust leakage, customizable round & square sizes for thermal power, cement and coking industry.

Main Structure

Consists of valve frame, wear-resistant gate plate, electro-hydraulic push rod actuator, sealing assembly, limit switch and control cabinet. The integrated electro-hydraulic drive unit is compact, easy to install without extra hydraulic station.

Core Advantages

• Strong hydraulic thrust, stable opening/closing, no stuck when handling wet, sticky and high-viscosity materials.
• Multi-control modes: local manual, automatic timing, remote DCS linkage control.
• Multi-layer sealing design, zero leakage of dust and pasty materials under positive pressure.
• Built-in position lock, gate plate stays fixed at any opening to stabilize discharging volume.
• Low failure rate, convenient daily maintenance, long service life.
• Customizable circular and square flange sizes to match all silo outlet and chute dimensions.

Application Scope

• Power industry: raw coal silo outlet, CFB boiler front coal drop pipe, ash discharge pipeline.
• Cement & mining: raw material batching silo, ore powder conveying chute.
• Coking plant: coal tower feeding port, sludge mixing conveying pipeline.
• Applicable medium: raw coal, coal slime, sludge, mineral powder, limestone powder and all granular/pasty bulk materials.
