Bellow sealed gate valve

Highlight: Bellow sealed gate valve

Product introduction:

Bellows gate valves are mainly gate valves that use bellows as the sealing element for the valve stem. They are often used

in scenarios with strict requirements for valve stem sealing, such as in high-vacuum environments and nuclear industries. By

replacing the packing函 (packing gland) in ordinary valves with bellows or using them in combination with packing glands,

these valves can achieve zero leakage at the valve stem, preventing the leakage of radioactive materials or precious metals,

or maintaining high vacuum. The bellows expand and contract with the lifting of the valve stem, and their maximum working

pressure depends on the pressure resistance and fatigue strength of the bellows.

Product features:

1. Reliable sealing: The bellows of bellows valves have good sealing performance, which can effectively prevent medium leakage.

2. Long service life: The bellows of bellows valves have a long service life, which can reach 500,000 to 1,000,000 life cycles.

3. Light operation: Bellows valves are easy to operate, convenient for opening control, and have a simple structure for easy maintenance.

4. Rich styles: Bellows valves are available in various types, and different styles can be selected according to different uses and media.
