General Description:

Leakage from the valve gland (stem packing) is often a problem for environmental protection & sometime it is quite dangerous if such leakage is from a hazardous fluid or gas. STAVAL 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.


Design Feature:

Zero stem emission,Flexible wedge,Graphite stem packing secondary seal,Threaded or welded seat ring,5,000 cycles bellow without failure

Application:

Refinery,Petrochemical,Solar energy power plant,Hot oil, steam supply,General Chemical Industry
