Electric Actuated Flange Butterfly Valve D941X-10/16 DN50-DN1200 for Water Treatment
Product Overview: Electric Actuated Flange Butterfly Valve
Model: D941X Series (or your specific model)
Application: Water Treatment, HVAC, Industrial Pipelines
The Electric Flange Butterfly Valve is a high-performance automation valve designed for precise flow control and reliable shut-off in industrial piping systems. Featuring a compact rotary-stroke electric actuator (yellow housing) mounted on a robust ductile iron butterfly valve (blue body), this unit combines durability with intelligent control.
Whether for on/off switching or modulating flow (4-20mA), this valve offers a cost-effective solution for modern fluid control.
1. Key Features & Advantages
Intelligent Electric Actuator:
a, Equipped with a high-torque electric actuator featuring a clear position indicator.
b, Supports On/Off or Modulating (Regulating) control modes.
c, Built-in manual override (handwheel) allows operation during power outages.
Superior Sealing Performance:
a, The valve body features a Resilient (Soft) Seat (EPDM/NBR), ensuring zero leakage and low operating torque.
b, The disc is streamlined to reduce fluid resistance significantly.
Robust Construction:
a, Valve Body: Made of high-strength Ductile Iron (GGG40/50) with anti-corrosive epoxy coating (Blue).
b, Disc: Stainless Steel (SS304/SS316) or Ductile Iron with Nylon 11 coating for excellent corrosion resistance.
Easy Installation & Maintenance:
a, Flange Connection design conforms to international standards (ISO/DIN/ANSI), making it compatible with most piping systems.
b, Compact structure saves installation space compared to gate valves.
