Product Overview
This electric soft-sealed gate valve combines a ductile-iron body with an EPDM-encapsulated ductile-iron wedge, delivering bubble-tight shutoff across the full pressure range. The straight-through flow path yields minimal pressure loss, making it ideal for raw water, treated water, and HVAC circulation lines.
The valve can be supplied with rising or non-rising stem, paired with a multi-turn electric actuator featuring overload protection, manual override, and remote open/close/stop signals.
Key Features
- Bubble-Tight Shutoff: EPDM encapsulated wedge delivers zero leakage across pressure range
- Low Pressure Loss: Full-bore straight-through flow path matches pipe ID
- Resilient Wedge: Solid EPDM rubber fully molded onto ductile iron core
- Smart Electric Drive: Multi-turn actuator with manual override and remote telemetry
- Corrosion Resistant: Epoxy-coated inside and outside for long service life
