BELLOW SEAL GLOBE VALVE

Bellows seal globe valves work by using a compact structure that includes bellows for sealing the valve stem components. The bellows valve has a bellow inside, and the lower end of the stainless-steel bellows is welded to the stem to prevent the system fluid from eroding the stem.

DESIGN FEATURES:
  • Non-rising handwheel: Free from foreign substance trouble because most threaded surface is covered.
  • No leakage by two-stage sealing of double bellows and gland packing. 
  • Gland packing does not need retightening nor applying pressure on spindle, thus handwheel can be turned with small torque without interference from the spindle.
  • Maintenance-free: No need to replace or retighten gland packing.
