Manual bellows stop valve

Overview:

The manual bellows stop valve adopts a bellows structure inside. The lower end of the stainless steel bellows is welded to the valve stem to prevent the process fluid from corroding the valve stem. It adopts a dual sealing design. If the bellows fails, the valve stem packing will also prevent leakage. The bellows is welded to the valve stem to maintain stable operating performance and avoid valve stem vibration caused by valve plug vibration. The top of the valve is equipped with a handwheel and a valve stem, and a threaded and stuffing box sealing section is provided in the middle. It is applicable to pipelines carrying various media such as steam, flammable, explosive, heat transfer oil, high-purity and toxic substances.
