Bellows Seal Globe Valve from Chinese Manufacturer

Our ASME bellows seal globe valves and gate valves are engineered for zero stem leakage in demanding industrial piping systems.

Product Application

Heat transfer oil and other highly permeable media: Operating temperature ranges from -29℃ to 425℃. It prevents medium loss in closed systems and environmental pollution.
Vacuum systems: For applications requiring strict packing sealing, it stops air backflow that would damage pipeline vacuum degree.
Steam media: Avoids heat loss and safety hazards caused by medium leakage.
Toxic media such as chlorine, hydrogen, HF acid, phosgene and ammonia water: Prevents medium leakage to protect the environment and eliminate safety risks.

Triple sealing design consisting of upper seal, packing and bellows. The bellows seal meets micro-leakage requirements; packing and upper seal serve as backup safety seals.
Built-in bellows with anti-impact and anti-rotation design, maximizing the service life of bellows.
Outside screw & yoke (OS&Y) rising stem structure. The stem is quenched and surface nitrided, delivering excellent anti-corrosion and wear-resistant performance.
Multi-layer bellows, manufactured with imported flexible, corrosion-resistant and high-temperature resistant metal bellows sealing technology.
Eliminates the defect of rapid aging and easy leakage of packing seals on conventional globe valve stems.
Anti-rotation structure installed at the upper connection of bellows. The built-in anti-rotation structure protects bellows from abnormal external damage and effectively extends service life.
