Bellows Expansion Joint
Bellows model
NK-14000 Pressure Balance Bellows Expansion Joints
Features
NK-14000 is the most suitable bellows expansion joint for the straight-line plumbing, having one balance
bellows twice as spacious as that of normal one in the middle of the two expansion bellows at the both
edges. Each bellow is connected with tie rod or tube, which offset the inner motives effectively.
The anchor is free from inner moving force, so its durability and cost performance can be enriched.
On the other hand, the reaction force of spring works caused by expansion-contraction movement.
