It can be customized according to different needs.

Product Overview
Electric Eccentric Semi-Globe Valve is a high performance cut-off valve, combining the advantages of eccentric structure and electric actuator. Its main features include:
1. High efficiency and energy saving: straight-through flow path design, small flow resistance, suitable for large flow rate transportation.
2. Reliable sealing performance: eccentric structure design, the sealing surface closely fits when closing, and the sealing surface is completely disengaged when opening, reducing wear and tear.
3. Easy operation: electric actuator can realize remote control and automatic operation.
4. Convenient maintenance: top-mounted structure, easy to replace and maintain damaged parts.

V. Material

Valve body material
Ductile iron (GGG45): good strength and toughness, suitable for low and medium pressure conditions.
Carbon steel (such as WCB): suitable for higher pressure and temperature conditions.

Valve seat material
Stainless steel (such as 304, 316): strong corrosion resistance, suitable for corrosive media.
Cemented carbide: for hard sealing conditions, can withstand higher temperatures and pressures.

Valve flap (ball) material
Stainless steel (such as 304, 316): strong corrosion resistance, smooth surface, reduce the medium on the sealing surface of the abrasion.
Carbon steel (such as WCB): high strength, lower cost, suitable for non-corrosive media.

Seal ring material
Nitrile rubber (NBR): good oil resistance, wear resistance, suitable for oil-containing media and water media.
Fluorine rubber (FPM): high temperature resistance, chemical resistance, suitable for strong corrosive media.
Polytetrafluoroethylene (PTFE): high temperature resistance, chemical corrosion resistance, low coefficient of friction, excellent sealing performance.
EPDM: good water resistance, strong aging resistance, suitable for clear water and weak acid and alkali media.

Valve stem material
Stainless steel (such as 20Cr13, 304, 316): strong corrosion resistance, high strength, suitable for use with valve body and valve flap materials.

Electric actuator
Shell material: aluminum alloy or stainless steel, strong corrosion resistance.
Motor: high torque motor, suitable for frequent opening and closing conditions.
Control unit: support a variety of control signals, such as 4-20mA, switching signals, etc., which can realize remote control and automation operation.
