Features
1. Corrosion resistance: almost resistant to corrosion by all media (including concentrated nitric acid and aqua regia).
2. Good sealing performance: double sealing with bellows and packing ensures no external leakage.
3. Small leakage: Since the valve core and valve seat adopt soft seals, the leakage is low.
4. Equipped with HA actuator, it has large output force and compact structure.
