Detailed Description

Hydraulic cylinder piston rod connects gate, the operation principle of manual hydraulic knife gate valve is that through manually handle, manual- driven hydraulic pump makes hydraulic fluid in the upper and lower chamber of hydraulic cylinder to drive gate opened and closed to achieve valve's open and closed. 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, Model: QUZ773X-10C Exterior structure: lugged Size: 2’’ -32’’ Pressure standard: GB, ANSI, JIS, DIN, BS Body: cast iron, ductile cast iron Disc: 201, 304, 316, 316L Connection: flange, wafer Seat ring: NBR, EPDM Sealing filler: PTFE Media: swage, power, paper pulp, ore pulp, cinder
