Custom T key operation extend stem gate valve underground use Manufacturer, Factories
Product Description
Technical Specifications
Characteristics
This T-key extended stem buried gate valve is made of epoxy coated ductile iron against soil corrosion and ground settlement. Customizable long stem with T-shaped head allows easy operation with matched wrench without road excavation. Full bore soft seal design provides tight zero leakage and low flow resistance, widely applied in deep buried water supply, fire protection and irrigation underground pipeline projects.
Key Advantages
T-shaped operating head bears force evenly, matching standard T-wrench for labor-saving operation, easier to handle than square head with common municipal maintenance tools.
Customizable extended stem fits different burial depths, solving operation problems of deep buried pipelines with wide application range.
Ductile iron body resists pressure and soil corrosion. Elastic soft seal achieves stable zero leakage with low failure rate for long underground service.
