Product introduction:


Bellows gate valves mainly refer to gate valves that use bellows as the sealing element for the valve stem, and are often

used in scenarios with strict requirements for valve stem sealing. By replacing the packing 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, precious metals, or maintaining a high vacuum state. 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.
