2 Gate Valve
The 2 inch gate valve is a common pipeline control device, mainly used for regulating and controlling the flow of fluids. Sorted by materials there are serval types of common 2 inch gate valve in the market:
- 2 inch stainless steel gate valve featuring corrosion-resistant construction with an aluminum handwheel and 316 stainless steel non-rising stem, bonnet, body, and wedge, these gate valves are ideal for refinery, chemical, and other process applications.
- 2 inch brass gate valve, designed with cast-iron wheel handles and brass discs, wedges, stems, and screw-in bonnets, these full port main shutoff valves can be used fully open or fully closed in water and compressed air applications. The non rising stems can be used in limited vertical space.
- 2 inch caron steel gate valve, cast steel valves are suitable for gas, oil, steam, water, and general service applications. The external valve stem threads prevent contamination from flow media.
- 2 inch bronze gate valve acting as a positive shutoff, these full port valves can be used fully open or fully closed in steam, water, and compressed air applications.
Main features of the 2 inch gate valve.
- High Corrosion and Impact-resistance
- Flexibility covering flow variations
- Easy maintenance
- Highly selective, can choose forged valve body or cast valve body, ASTM A182 /ASTM A216/ ASTM A351 standard available, pressure classes from 150 lb to 1500 lb
- The stem connection to the wedge of 2 inch gate valve is a T-head design that is integral (without welding) to the stem. The accuracy in the dimensions and finishes assure a long life with a perfect tightness in the packing area, resulting in lower fugitive emissions;
- The stem packing is designed and arranged to ensure a maximum seal along the stem during operation or while at the position, thus allowing for a greater reduction in fugitive emissions. Our packings are NON-ASBESTOS types;

Applications of 2 inch gate valve.
2 inch gate valve is widely applied in various fields such as petroleum, chemical engineering, metallurgy, and electric power.
How many turns on a 2 inch gate valve?
The number of turns on a 2-inch gate valve can vary depending on the specific design and manufacturer. However, typically, it may require around 5 to 10 full turns to fully open or close the valve. This is just a rough estimate, and the actual number of turns should be determined based on the valve’s documentation or by observing its operation during installation and commissioning.
