The Electric Soft Seal Flange Gate Valve is an advanced,automated fluid control valve designed for reliable on/off and isolation duties in low-to-medium pressure piping systems.It integrates a high-performance electric actuator with a resilient soft-sealed gate mechanism,delivering bubble-tight shutoff,smooth operation,and long service life.Primarily engineered for water,wastewater,and neutral industrial fluids,it is widely deployed in municipal water supply,sewage treatment,construction,power,and general processing plants.

Key Design Features

Superior Soft Sealing Performance

Gate is fully encapsulated with high-grade elastomers(EPDM/NBR)for zero leakage(bubble-tight).

Elastic deformation compensates for minor seat imperfections,ensuring consistent,reliable sealing.

Self-cleaning action during operation wipes away debris,preventing seal damage.

Flat-Bottom,Non-Clogging Valve Body

Unique flat-bottom seat design eliminates cavities where sediment,sand,or solids can accumulate.

Smooth,full-bore flow path minimizes flow resistance and pressure loss.

Ideal for dirty water,sewage,and media with high solid content(up to 40%solids).

Robust Electric Actuation

Equipped with an intelligent electric actuator(on-off or modulating type).

Provides remote control,automatic operation,and position feedback.

Integrates with PLC,DCS,and SCADA systems for full automation.

Emergency manual override available for power failure.

High protection grade(IP67/IP68)for submerged or harsh environments.

Durable Construction&Low Maintenance

Body constructed from ductile iron(GGG50),carbon steel(WCB),or stainless steel(CF8/CF8M).

Internal and external epoxy coating for excellent corrosion resistance.

Triple"O-ring"stem seals for reliable stem sealing and in-service replacement capability.

Bolted bonnet design for easy access and maintenance.

Long MTBF(Mean Time Between Failures)and minimal maintenance requirements.
