*Threaded Flange Cold-forged Steel Gate Valve
### Specs
- Threaded flange cold-forged steel gate valves usually follow the DIN standard.
- Size range DN25 and pressure class PN16.
### Materials
- The valve body is usually made of ASTM A105N.
### Apps
- This gate valve is suitable for general oil, gas and water applications with a temperature range from -29°C to 425°C.
- Primarily designed for on/off service when straight flow and unobstructed fluid flow is required.
### Maintenance
- The stem should be inspected and lubricated regularly to ensure ease of operation. Lubrication of the stem should be done every six months or more depending on the installation environment.
- Stem packing should be inspected at least every six months to ensure there are no leaks.
- For water and oil services, regular maintenance should be performed, and for more aggressive media, monthly inspections and maintenance should be carried out.
- Maintenance and repair work must be carried out after the valve is fully depressurized, and welding repairs must not be carried out while the valve is working.
