Bellow Seal Gate Valve
Product Overview
Bellow Seal Gate Valves for Industrial Shut-Off Applications
A bellow gate valve is designed to open or close the flow passage through a piping system. In a bellows-sealed arrangement, a flexible metallic bellows provides an additional sealing barrier around the valve stem.
Conventional gate valves commonly use stem packing to limit leakage. A bellows seal introduces another barrier between the process fluid and the external environment.
This can be useful in selected applications involving fluids that require careful containment. However, the bellows material, pressure rating, temperature capability and expected operating cycles must be suitable for the service.
A bellow seal gate valves supplier should be able to discuss the valve construction, available materials and application requirements before final selection.

Working Principle
Bellow Seal Valve Working: How Does It Operate?
Understanding bellow seal valve working involves two separate functions: controlling flow through the gate and sealing the moving stem.
01
Opening the Gate
Operating the hand wheel or actuator moves the stem and lifts the gate out of the flow path.
02
Bellows Movement
The metallic bellows extends or compresses with stem movement while maintaining a sealing barrier around the stem.
03
Closing the Gate
The gate moves back into the flow path and seats to isolate the process flow.
Gate valves are generally intended for fully open or fully closed service, rather than continuous throttling. Bellows integrity and service life depend on the actual valve design and operating cycles.
Material Selection
Shell and Trim Materials for Bellow Seal Gate Valves
Selecting the correct materials is important for any industrial gate valve, particularly when the application requires careful control of external leakage.
The supplied shell material list includes WCB, LCB, LCC, WC1, WC6, WC9, C5 and C12.
Stainless steel options include CF8, CF8M, CF3, CF3M and CF8C. Other listed materials include duplex stainless steel, Hastelloy, Inconel and additional special alloy grades.
Trim material options include 13% chromium steel, 304, 304L, 316, 316L, 321, 347, F51 and Monel.
The bellows material is a separate selection consideration and should be confirmed for the process medium, pressure, temperature and operating cycle requirements.
