ANSI Bellow Sealed Globe Valve - Cast Steel Globe Valve with Bellow

General Description: Leakage from the valve gland is often a problem for environmental protection & sometime it is quite dangerous if such leakage is from a hazardous fluid or gas. FLOWTEK bellow sealed valves are designed with a bellow cartridge which welded to the valve bonnet and stem, so that when the stem up & down movement makes the bellows expands & compress. Therefore there is no sliding or rotating seals through which process fluid can leak.
