  • DESCRIPTION

    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.
