E9700 High Performance O-Port Knife Gate Valve

E9700 High Performance O-Port

Knife Gate Valve

The E9700 High Performance O-Port Knife Gate Valve (Through Conduit) is specifically designed for the mining, pulp & paper, and power generation industries. The pressure assisted seat design provides reliable, bidirectional shutoff in various applications such as slurries, dry materials, static columns, high consistency stock, black/white/green liquor, wood chips, and highly viscous fluids.

Features & Benefits

  • Through Conduit design ensures reliability on static columns and dry materials
  • Spring loaded seat design provides improved process sealing
  • Full port opening allows maximum throughput and minimizes pressure drop
  • Oversize flushing ports allow elimination of material buildup
  • Live loaded PTFE packing provides reliable sealing
  • Lockout pin provision ensures operator and maintenance safety
  • High visibility clevis provides easy identification of valve position
  • ISO 5211 mounting pattern allows direct mounting of various actuation options including bevel gear, pneumatic or hydraulic cylinders, and electric actuators
  • Grease fitting on handwheel bearing reduces operating torques
