Product Description
The valve can bear high work pressure difference due to its fluid pressure balanced spool structure; besides of features in general single-seat control valve, its special guide structure of balanced sealing-ring trim enables it to be in sound dynamic stability; compared with various cage-guided control valve, it is more suitable for the work conditions where the medium contains particles and impurities because it is not easy to block the spool, and specially proper for the harsh work conditions with large specifications, high pressure difference (no cavitation).
