Key Features & Advantages:

1. Electric Actuation for Automated Remote Control

• Convenient Operation: The electric actuator enables open/close control from a control room, reducing labor costs and improving response time.

• Local & Remote Control: Standard configuration includes manual override handwheel and position indication for local use.

• Voltage Flexibility: Actuator voltage customizable (e.g., 110V, 220V, 380V, 24V DC) based on site requirements.

 

2. Non-Rising Stem (NRS) Design for Space-Constrained Installations

• Vertical Clearance Saving: The stem does not rise when the valve opens, making it suitable for buried pipelines, valve pits, and installations with limited headroom.

• Reliable Stem Protection: The stem threads are enclosed and lubricated, protected from debris and corrosion.

 

3. Resilient EPDM Seat for Bubble-Tight Shut-Off

• Zero Leakage: The EPDM rubber seat is compression-molded onto the ductile iron body or gate, providing a tight seal that meets or exceeds Class VI requirements for water service.

• Excellent Media Compatibility: EPDM is resistant to water, wastewater, mild chemicals, and weathering.

• Low Torque Operation: The resilient seat reduces friction between the gate and seat, lowering actuator torque requirements.

 

4. Ductile Iron Body for Strength and Durability

• High Mechanical Strength: The body is cast from GGG40/500-7 ductile iron, offering superior tensile strength and impact resistance compared to gray iron.

• Corrosion Protection: Standard epoxy coating (minimum 250μm) protects against atmospheric and soil corrosion for buried service.

• Long Service Life: Ductile iron resists pressure surges and mechanical stress common in large-diameter water mains.

 

5. Full Port Design for Minimal Pressure Drop

• Unobstructed Flow Path: When fully open, the gate retracts completely into the bonnet, providing a full bore that does not restrict flow.

• Energy Efficient: Reduced pressure drop lowers pumping costs in high-flow systems.

 

6. Customizable Flange and Actuator Options

• Flange Standards: Available with EN 1092-2 PN10/PN16, ANSI B16.1 Class 125, or other standards per request.

• Accessories: Can be equipped with manual override, positioner, heater, or explosion-proof housing.
