Characteristics
This electric gate valve features a rugged ductile iron body and precision-machined brass alloy hard sealing surfaces. It integrates the high strength and shock resistance of ductile iron with the excellent wear resistance and corrosion resistance of brass, ensuring stable and long service life under various working conditions.
Advantages
1.Excellent sealing performance and long service life
The GGG50 gate valve with copper alloy sealing surface has high hardness, wear resistance, and erosion resistance, making it more durable than ordinary cast iron seals. It is not easy to scratch or leak, has multiple opening and closing cycles, and can maintain a tight seal even after long-term use.
2.Electric control, high degree of automation
The bronze seat gate valve equipped with electric actuators, capable of remote switching and automatic control, and connected to PLC/DCS systems; Equipped with limit and overload protection, stable operation, reduced manual on-site operation.
3.Bi-directional sealing, easy installation
This gate valve without flow restrictions, can be installed in both directions, flexible on-site construction, and simple maintenance
Packing
Standard export wooden case packaging
Application Scenarios
The electric operate hard seal gate valve suitable for municipal water supply and drainage, building fire protection, water conservancy pump stations, and industrial circulating water systems, achieving remote automatic opening and closing and reliable cut-off of pipeline media.
