Non-groove electric knife gate valve
Cast Iron, with the overall structure, electric knife gate valve
includes body, disc and U-seal, groove and flexible U-seal at the
bottom of the cavity. Disc is moved down when valve is closed, the
bottom edge of disc meets with the seal and then compresses into
the groove to achieve sealing. Disc is moved up when knife gate
valve is opened, the bottom edge of disc breaks from seal,
Seal bounces up with groove formation to prevent media accumulated
in the body cavity, not blocked easily and residue, pipe is cleaned
easily, and to prevent leakage when knife gate valve is closed
.That improves knife gate valve's sealing effect effectively. With
longer service life, simply maintenance ,flange O-ring sealing ,
without changing flange gasket, simply installation and small
friction coefficient ,flexibly opening and closing, the series
knife gate valve can be equipped with electric and controlled
through on-site boxes, on-site Denso button and remote PLC
intelligent to achieve open and close. Users can choose based on
themselves needs.
