1. Bellows sealed wedge forged steel gate valve adopts forged steel body with metal bellows stem sealing structure, eliminating the risk of external leakage at stem packing, specially designed for small bore, high pressure and low emission service.
2. The valve is designed in accordance with API 602 and MSS-SP-117 standards, suitable for toxic, hazardous and volatile media.
3. Materials for forged body and wedge, bellows can be selected as required.
4. Applied in chemical, pharmaceutical and coal chemical plants to prevent outward leakage of toxic and hazardous media from stem packing.
1. Wedge gate sealing delivers reliable shut-off performance.
2. Metal bellows acts as primary seal to block media escape through stem packing area.
3. Backup packing is equipped as secondary protection to upgrade equipment safety level.
4. Forged steel body features superior internal quality, high pressure resistance and zero casting defects.
5. Bellows has passed fatigue cycle tests to suit frequent on-off operation and ensure safe service.
6. Anti-blowout stem structure guarantees safe equipment operation.
7. The stem is isolated from external surroundings, eliminating fugitive emission pollution to protect environment and operators.
