Description
Description:
| Gate valves are essential components in fluid control systems. They regulate fluid flow by utilizing a gate or wedge-shaped disc that moves perpendicular to the flow direction. This design makes them suitable for both liquid and gas applications, depending on the valve’s material composition.
Newcomen Engineering Valve Company will design and manufacture all type of Gate valves to meet customer requirements. These valves will be available in a range of sizes, pressure classes, and materials, tailored to specific process needs. |
Material:
Body and Bonnet Material:
Forged Gate Valve
- Carbon Steel:
- ASTM A105: A common choice for general-purpose applications.
- Alloy Steel:
- ASTM A182 F1: Suitable for higher temperature and pressure applications.
- ASTM A182 F9: Offers good resistance to corrosion and oxidation.
- ASTM A182 F11: Provides excellent resistance to high temperatures and pressures.
- Stainless Steel:
- ASTM A182 F304/304L: Offers good corrosion resistance and is suitable for a wide range of applications.
- ASTM A182 F316/316L: Provides excellent resistance to corrosion, particularly in chloride-containing environments.
