Bellow Sealed Valves
Bellow seal valves are designed with bellow welded into the bonnet and stem so that when the stem travels drive the below expansion or decompression, it inherently eliminate the conventional design of possible stem packing leakage. Sanseco bellow sealed valves can achieve truly zero leakage and they are ideal for stringent leakage-free application like toxic and flammable services.
