Univers 1600
Manual cryogenic globe valve
Univers 1600: valve series for use at cryogenic temperatures down to LHe (1.8 K). Supplied with standard welding flange for vacuum jacketing (optional sizes on request). The valve body optimizes the heat input and shows optimized flow rate (Kv value). Sniffle hole (G 1/8”) to detection chamber/pressure control for supervision of bellow tightness.
Options: Soldered Cu flange as thermal coupling positioned along the extended stem. Sliding thermal contact to cool the valve plug stem from the valve extension outer tube. High-flow surface treatment available (electro-polishing) for decreased blistering.
