3 Inch Gate Valve

3 inch Gate valves are used to cut off or connect the medium in the pipeline. Using different materials, it can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, etc., and is widely used in oil pipelines. Most hardware gate valves are a reduced bore design. Compared with the cast steel gate valve of the same diameter, the flow rate is slightly smaller, but the pressure and temperature range it withstands is higher than that of the cast steel valve, and the sealing performance is much better than that of the cast steel gate valve. Longer life, medium flow direction is not restricted by other gate valves.

The main alternative material

Carbon steel class: WCB, WCC, A105, etc

Class: stainless steel 304, 316, 304 L, 316 L, CF8, CF8M, CF3, CF3M, CF8C and duplex stainless steel, etc.

Class: low-temperature steel LF2, LCC, LCB, etc

Chrome molybdenum steel types: WC5 WC6, WC9, C5, etc

Gate valves have the following advantages:

1. Simple structure, easy to manufacturer and maintain

2. Small working stroke and short opening and closing time

3. Good sealing performance, small friction between sealing surfaces and long life

4. In the process of opening and closing, the friction of the sealing surface is smaller than that of the gate valve, which is wear-resistant

5. Usually only one sealing surface, good manufacturing process, easy to maintain
