Product Introduction

The bellow seal forged globe valve is made with imported advanced metal bellows sealing technology. High performance elastic metal bellows, stretching fatigue life is particularly long. Compared with normal valve stem packing seal, the bellows seal design of bellow seal forged globe valve completely eliminates the defects of easy aging and leakage. It not only improves energy efficiency, increases safety of production equipment, reduces maintenance costs and frequent maintenance, but also provides a clean and safe working environment.

Features

1. Double seal design (bellows + packing) If the bellows fails, the stem packing will also avoid leakage and comply with international sealing standards

2. No fluid loss, reduce energy loss and improve plant equipment safety

3. Long service life, reduce maintenance times and operating costs

4. Rugged and durable bellows seal design ensures zero leakage of the valve stem and provides maintenance-free conditions

5. The gas medium valve seat adopts PTFE soft sealing material to improve the tightness of the valve

6. Valve seat with high temperature resistance ≤425℃ adopts conical hard seal. Achieve airtight performance with zero leakage
