Bellow-Seal Valve Features
Our bellow-seal valves are engineered to deliver leak-proof performance and long-term reliability in critical applications. Designed to eliminate stem leakage, each valve undergoes rigorous testing as per API 598 standards, while every bellow assembly is helium leak-tested to ensure zero emissions. The non-rotating stem design prevents torsional stress, enhancing durability and operational life.
For added safety, these valves include secondary stem sealing features such as stem backseat and API 624 compliant packing. Integrated lubricant fittings ensure smooth operation and reduced wear during opening and closing cycles. Manufactured using high-grade materials like 316Ti, Hastelloy, Inconel, and Monel, the bellows are hydroformed with multi-layer construction for superior strength.
Bellow-Seal Valve Features
Bellow-seal valves are specially designed to provide zero leakage performance in critical applications where safety and emission control are essential. These valves use a welded bellow assembly to completely isolate the fluid from the environment, ensuring long-term reliability and protection against hazardous leaks.
- Each valve is tested per API 598
- Every bellow assembly is helium leak-tested to assure zero leakage.
- Non-rotating stems prevent torsion of bellow.
- Secondary stem seals include:
- Stem backseat
- API 624 stem packing
- Lubricant fittings to ensure proper lubrication of stem bushing for efficient opening and closing.
- Multiple bellows materials are available: 316Ti, Hastelloy, Inconel, Monel, etc.
- All bellows are hydroformed with a minimum of two layers.
- Available in pressure classes 150-1500 (All body materials available)
