Cryogenic Globe Valve – YONCO PN16 to PN40
The YONCO Cryogenic Globe Valve (DJ41Y / DJ41W) is a premium isolation and flow control valve engineered specifically for extreme low-temperature fluid handling and storage systems. Designed for critical applications ranging from -45°C down to -196°C, this valve provides exceptional sealing integrity and flexible operation. It is the ultimate choice for safely managing cryogenic media such as Liquefied Natural Gas (LNG), liquid ethylene, and liquid propylene across deep cold processing, gas separation, and cryogenic transportation sectors.
Core Features & Advantages
- Extended Bonnet Design: Engineered with an extended neck to protect the stem packing from extreme cold temperatures, preventing freezing and ensuring smooth, reliable manual operation without leakage.
- Premium Cryogenic Materials: The valve body and bonnet are cast from specialized low-temperature carbon steel (LCB) or nickel alloy steel (LC3) to maintain high impact toughness and prevent brittle fracture at deep sub-zero temperatures.
- Wear-Resistant Hard Facing: The disc and seat sealing surfaces are hard-faced with Cobalt-Chromium-Tungsten (Stellite) alloy, delivering superior resistance to wear, galling, and extreme cryogenic thermal shock.
- Flexible & Reliable Shut-off: Precision-machined stem and disc components allow for highly responsive opening and closing with minimal torque, ensuring bubble-tight isolation even under severe thermal contraction.
- Strict Cryogenic Treatment: All critical components undergo rigorous sub-zero treatment and dimensional stabilization prior to assembly, guaranteeing absolute structural integrity and sealing reliability in the field.
