ANSI Bellows Seal Gate Valve

Product Description

ANSI Bellows Seal Gate Valve provides bidirectional protection (bellows and packing). The combination of bellows and packing ensures effective sealing.

ANSI Bellows Seal Gate Valve Advantages:

• Bellows seal component. Metal bellows effectively prevent leakage in the valve stem portion.

• Operating temperature range: -196℃ to 600℃

• Zero maintenance for reduced operational costs/no downtime

• Comfortable handwheel shape for easier operation and longer lifespan.

What is the different between bellow globe valve and bellow gate valve?

1. The bellow seal globe valve is longer than bellow seal gate valve, so pipe line prefer to choice bellow globe valve.

2. Different flow and functions, bellow seal globe valve can not only be used as a cut-off, but also can be used to regulate and control the pressure flow. The bellow seal gate valve is usually used for isolation. Bellow seal globe valve no need full open，the gate valve generally needs to be fully opened or closed.

3. Different installation methods

When use bellow globe valve, the medium can generally be from top to bottom. When medium flow in bellow seal gate valve, there is no no requirement on the direction of import and export.

4. When the bellow seal globe valve working, its handwheel and valve stem are generally rotating together, and will do the lifting action together, the bellow gate valve generally only the handwheel will rotate, besides it only do the lifting action.

ANSI Bellows Seal Gate Valve Applications:

Cast steel bellow seal gate valve is suitable for applications where valve leakage in or out is not permitted, such as heat transfer oils, toxic fluids, steam, and regulating mediums.

AFBV bellows technology prevents corrosive or harmful atmospheric conditions from entering the process.
