Electric Ball Valve
Categories：
Eccentric Half Ball Valve
Email: official@zzvalves.com
It can be customized according to different needs.
Product Overview
The electric eccentric ball valve is a high-performance shut-off valve that combines the advantages of an eccentric structure and an electric actuator. Its main features include:
1. High efficiency and energy saving: Straight-through flow channel design with low flow resistance, suitable for large flow delivery.
2. Reliable sealing performance: Eccentric structure design, the sealing surface fits tightly when closed and completely disengages when opened, reducing wear.
3. Easy operation: The electric actuator enables remote control and automated operation.
4. Easy maintenance: Top structure, easy to replace and maintain damaged parts.
Usage Scenarios
1. Urban water supply and drainage systems
Application scenarios: urban water supply pipelines, drainage pipelines, sewage treatment plants, etc.
2. Long-distance water diversion projects

V. Materials
Valve body materials
Ductile iron (GGG45): good strength and toughness, suitable for low to medium pressure conditions.
Carbon steel (such as WCB): suitable for higher pressure and temperature conditions.
Valve seat materials
Stainless steel (such as 304, 316): strong corrosion resistance, suitable for corrosive media.
Hard alloy: suitable for hard-seal conditions, can withstand higher temperatures and pressures.
Valve disc (ball) materials
Stainless steel (such as 304, 316): strong corrosion resistance, smooth surface, reduces wear on sealing surfaces by the medium.
Carbon steel (such as WCB): high strength, low cost, suitable for non-corrosive media.
Seal ring materials
Nitrile rubber (NBR): good oil resistance and wear resistance, suitable for oil-containing and water media.
Fluororubber (FPM): high temperature resistance and chemical corrosion resistance, suitable for strongly corrosive media.
Polytetrafluoroethylene (PTFE): high temperature resistance, chemical corrosion resistance, low friction coefficient, excellent sealing performance.
EPDM: good water resistance and aging resistance, suitable for clean water and weak acid-base media.
Valve stem materials
Stainless steel (such as 20Cr13, 304, 316): strong corrosion resistance and high strength, suitable for matching with valve body and valve disc materials.
Electric actuator
Housing material: aluminum alloy or stainless steel, strong corrosion resistance.
Motor: high torque motor, suitable for frequent opening and closing conditions.
Control unit: supports multiple control signals such as 4-20mA, switch signals, etc., enabling remote control and automated operation.
