PFA Lined Bellow Sealed Globe Control Valve
PFA Lined Bellow Sealed Globe Control Valve
Richter offers RSS Series PFA Lined Bellow Sealed Globe Control Valve which is used for biotechnology and high-purity media where good cleaning and anti-adhesive surfaces are important. PTFE bellows hermetically seals the product chamber from the atmosphere and protect the valve stem against corrosion. The V-plug made of compression proof and dimensionally stable TFM-PTFE has 1 to 4 grooves, depending on the kv/Cv value. When the valve opens, the V-grooves offer an expanding opening cross section whilst the plug is always guided in the seat. This ensures high-quality control even at elevated temperatures and differential pressures. A dynamic sealing lip integrated into the seat limits the flow precisely to the V-grooves, thus preventing undesired leakage. A PTFE cord prevents the plug from unscrewing. Hastelloy or tantalum plug inserts, which were previously used for stability and accuracy reasons, can now be dispensed with.
