Bellows Globe Valve

Product Introduction

Bellows globe valve‌is a valve that controls the flow rate through bellows sealing technology. Its core lies in the bellows structure, which can absorb the thermal expansion and mechanical vibration of the pipe while maintaining the tightness. The design of the bellows globe valve completely eliminates the disadvantages of fast aging and easy leakage of ordinary valve stem packing seals. It improves energy efficiency, increases the safety of production equipment, reduces maintenance costs and frequent maintenance, and provides a clean and safe working environment.‌

Product Advantages

1. Double sealing design‌: Bellows globe valve adopts double sealing design of bellows and packing. Even if bellows fails, packing can prevent leakage to ensure zero leakage of valve stem and meet international sealing standards‌.

2. The bellows globe valve uses a closed bellows that can be stretched and compressed instead of the packing and sealing, effectively preventing external leakage caused by packing loss, and is especially suitable for the transportation of highly permeable media, such as hydrogen systems‌.

3. The bellows globe valve is suitable for high temperature and high pressure working conditions. The unique self-sealing design makes the higher the pressure, the more reliable the sealing‌.

4. Bellows globe valves mainly include high-pressure bellows globe valves, stainless steel bellows globe valves, and carbon steel bellows globe valves.

• Design Standard: BS1873 / ASME B16.34,
  

• End Flange: ASME B16.5 / JIS B2212 / DIN 2543

• Face to Face: ASME B16.10 / JISB2002 / BS EN558-1

• Inspection and testing: API598

• The bellows globe valve has a simple structure, is easy to maintain, and has a good streamlined structure, which can effectively prevent fluid backflow and reduce flow resistance and noise.

• Part of the bellows globe valve is designed as a two-way seal, that is, it can effectively seal in both directions, increasing the flexibility of its application.

• Bellowed globe valve is suitable for‌petroleum,‌chemical industry,‌pharmaceutical,‌fertilizer, electric power and other industries‌,which is used to cut off or connect the pipeline medium on various working conditions. Its double-layer bellows design can effectively prevent valve stem vibration, suitable for high-pressure environments, and is widely used in‌food,‌medicine, petroleum, chemical industry and other fields.
