DI globe valve

The valve body boasts excellent corrosion resistance, aging resistance and high pressure resistance, adapting to various complex working environments such as outdoor exposure, underground pipe networks, high-temperature heating and continuous pressure operation. It features wide installation adaptability and minimal maintenance requirements. With superior stability and cost performance, it serves as the preferred cut-off and regulating valve for various pipeline engineering projects.

Detail

Parameters

The full name of the ductile iron globe valve is ductile cast iron globe valve. It is a widely used general cut-off and regulating valve

for water supply and drainage, heating, industrial pipelines and fire protection systems. Integrally cast from high-strength QT450

ductile iron, it features higher toughness, better impact resistance, higher pressure resistance and stronger deformation resistance

compared with traditional gray cast iron valves, effectively solving the common defects of ordinary cast iron valves such as easy fracture,

leakage and poor durability under frequent opening and closing.

Relying on the vertical lifting of the disc to realize pipeline cut-off and flow regulation, the valve integrates tight cut-off and precise

throttling functions. With stable operation, excellent sealing performance and high durability, it can adapt to various media such as water,

hot water, steam, oil and air for long-term service, serving as a core supporting valve for municipal engineering, HVAC systems

and industrial pipe networks.

Core Product Advantages（Ductile Iron Globe Valve）

✅ High-grade ductile iron material with superior performance

Adopting QT450 ductile iron featuring high toughness, strong impact resistance and high pressure resistance. It is not easy to crack or

deform, and withstands extreme temperatures and corrosion. It effectively solves the common defects of ordinary cast iron valves such

as easy fracture and leakage, and adapts to harsh working conditions.

✅ Dual functions of cut-off and throttling

It can not only completely cut off the pipeline medium to achieve zero leakage shutoff, but also precisely adjust the opening to fine-tune pipeline flow and pressure. It meets diverse working requirements of pressure stabilization, throttling and flow control, delivering

more comprehensive functions than ordinary gate valves.

✅ Tight sealing with zero leakage and no backflow

Adopting a forced sealing structure, the disc fits precisely with the valve seat to achieve excellent sealing performance after closing. It effectively prevents medium leakage and backflow, ensuring stable operation of the pipe network system.

✅ Stable operation with erosion and wear resistance

The optimized internal flow channel ensures smooth medium circulation and reduces flushing loss. The core sealing parts are

wear-resistant and anti-corrosive, maintaining stable performance under long-term frequent opening and closing with extremely

low failure rate.

✅ Wide adaptability with excellent temperature and pressure resistance

Applicable for various media such as cold water, hot water, high-temperature steam, oil products and air. It operates stably under both

high and low temperature conditions, widely suitable for civil and industrial pipeline systems.

✅ Simple operation and convenient installation & maintenance

Labor-saving manual opening and closing with adjustable opening and easy on-site commissioning. The simple structure has no complex

vulnerable parts, requiring no frequent daily maintenance and only regular sealing inspection, which greatly reduces operation and maintenance costs.

✅ Complete specifications and strong compatibility

Available in multiple calibers and pressure grades, supporting flange and thread connections. It is fully applicable to municipal, HVAC,

industrial and fire-fighting pipeline installation scenarios.
