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