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
