Y Type Bellows Seal Globe Valve Low Resistance Zero Leakage Industrial Globe Valve
Y Type Bellows Seal Globe Valve is an upgraded industrial globe valve optimized for low pressure loss and frequent operation working conditions.
‑ Unique Y‑shaped oblique flow channel design, greatly reduce fluid resistance and pressure drop
‑ Smooth medium flow, less energy loss than straight‑type globe valves
‑ Integral metal bellows sealing structure, achieve 100% stem zero external leakage
‑ Dual sealing system with bellows + backup packing, double safety guarantee
‑ No medium volatilization, suitable for toxic, odor and environmentally sensitive media
‑ Excellent high temperature resistance, anti‑fatigue for frequent opening and closing
‑ Accurate flow throttling and reliable tight shut‑off performance
‑ Dark rod non‑rising handwheel structure, space‑saving and safe operation
‑ High‑strength cast steel and stainless steel body optional
‑ Comply with DIN and GB industrial pipeline standards
‑ Support manual, pneumatic and electric drive customization
‑ Maintenance‑free bellows structure, reduce later operation cost
‑ Strict hydrostatic and sealing test before factory delivery
‑ Support OEM, ODM special working condition customization
‑ Complete material certificates and test reports provided
‑ Factory direct supply for long‑term industrial pipeline matching
Widely used in power plant, heating engineering, thermal oil circulation, chemical processing, pharmaceutical and environmental protection pipeline systems. Especially suitable for high‑temperature steam, viscous medium and process pipelines requiring frequent opening/closing and low pressure loss.
Y Type Bellows Seal Globe Valve adopts 45° Y‑shaped flow passage structure. The valve disc lifts and lowers linearly to realize fluid cut‑off and throttling. The inclined channel makes medium flow smoother and reduces turbulence and pressure loss. The fully welded metal bellows isolates the valve stem from internal medium, completely eliminating traditional packing leakage, ensuring long‑term stable and safe operation.
