SS316 Bellow Seal Globe Valve
An SS316 bellow seal globe valve is a type of globe valve that is made of stainless steel (SS316) and features a bellow seal. The bellow seal is a flexible metal or plastic seal that surrounds the stem of the valve. It helps to prevent leaks by providing an additional barrier around the stem, and it also helps to compensate for any thermal expansion or contraction that may occur. The bellow seal is particularly useful for high-pressure or high-temperature applications, as it can withstand these conditions better than traditional packing materials.
The SS316 material is an alloy of stainless steel that contains a higher percentage of molybdenum and nickel, making it more resistant to corrosion and high temperatures than other types of stainless steel.
The bellow seal on an SS316 globe valve provides an additional level of safety and reliability, helping to prevent leaks and prolong the life of the valve in demanding applications. the SS316 bellow seal globe valve works by controlling the flow of fluids through the valve by opening or closing the disc, which is connected to the stem and is operated by a handle or actuator. The bellow seal provides an additional level of safety and reliability by preventing leaks and compensating for thermal expansion and contraction.
Advantages of SS316 bellow seal globe valve:
- high resistance to corrosion
- low maintenance
- It provides an additional barrier around the stem to prevent leaks
Disadvantages of SS316 bellow seal globe valve:
- It has limited flow control
- These valves are more complex and have more moving parts, so it can increase the maintenance requirements.
- It is limited to pressure range.
