Product Description
Product Details
| Valve Type: | Metal seat gate valve | Structure: | Rising type |
| Standard: | EN/API/DIN/GOST | Workmanship: | Investment casting |
| Sealing Direction: | Bidirectional | Sealing Grade: | Zero leakage |
| Temperature: | -30°C < T < 425°C | Operation: | Handwheel |
Characteristics
The valve body adopts integral casting or forging technology, and the wall thickness is strengthened according to the pressure level, which can withstand pipeline water hammer impact and industrial site vibration. The valve stem and gate are rigidly connected (T-shaped groove+bolt/pin shaft) to prevent damage to the sealing surface caused by gate shaking.
Advantages
The valve body and valve cover are connected by flanges, and there is no need to disassemble the entire valve during maintenance. Only the valve cover needs to be removed to replace internal components such as gate plates, seals, and packing; The packing box supports online replacement of packing, which does not affect the normal operation of the pipeline and significantly reduces maintenance costs.
Carbon steel material (WCB) gate valve: Metal sealed structure, temperature resistance range -29℃ ~ 540℃, suitable for media such as water, oil, steam, etc.
Alloy steel material (WC6/WC9) gate valve: Temperature resistance up to 650℃, suitable for high temperature reheating steam pipelines in power plants.
Soft sealing structure (PTFE/EPDM): Temperature resistance range -20℃ ~ 180℃, suitable for low temperature and low pressure scenarios such as municipal water supply and drainage.
Packing
Application Scenarios
The large size gate valve widely used in large-diameter pipeline systems in industries such as oil and gas, electricity, municipal water supply and drainage, chemical engineering, metallurgy, and people's livelihoods.
