Bellow Seal Valves
The fluids in the pipes are often toxic, radioactive and hazardous and the atmosphere must always be protected by these chemicals. The bellow seal system is indispensable for this, because it completely closes and isolates the stem. In addition, the upper and lower parts are completely welded by means of spot welds, making the valve completely impermeable. A HELIUM LEAK test and PMI tests can be supplied at will.
