DN100 PN40 Cryogenic Globe Valve – CF8 Stainless Steel Extended Bonnet

Engineered for extreme sub-zero applications, this DN100 PN40 Cryogenic Globe Valve is precision-cast from CF8 (304) Stainless Steel. It features a specialized extended bonnet with a drip plate, ensuring the stem packing remains protected from freezing and guaranteeing smooth, leak-free operation at temperatures down to -196°C. Ideal for precise throttling and shut-off in LNG, liquid oxygen, and cryogenic chemical plants.

🏭 Engineering Highlights:

  • Body Material: CF8 (ASTM A351) Stainless Steel for cryogenic toughness.
  • Pressure Rating: PN40 (4.0 MPa) for high-pressure reliable sealing.
  • Design: Extended bonnet design specific for cryogenic media isolation.
  • Function: Excellent throttling characteristics and zero-leakage shut-off.
