Knife Gate Valve
The E5700 knife gate valve is designed and configured specifically for use in aggressive processes and high wear pulp & paper applications. The unidirectional, Class 150 design features a replaceable, hardened gate and seat ring to provide reliable cutting action in challenging applications that include fibrous materials. The E5700 can also be fitted with a serrated seat option for use on recycling applications.

Knife Gate Valve Accessories
Position Sensors
Position sensors utilize proximity probes and a magnetic target to detect the valve position and provide reliable feedback to a control system. Mounting directly to the yoke and detecting the position of the gate provides a more reliable solution than cylinder mounted switches. Hazardous area versions are available.
Solenoid Valve
Solenoid valves are used to control the opening and closing of a pneumatically actuated valve. A NAMUR style valve is typically used for rack pinion style actuators, and an inline valve is used for pneumatic cylinders. They are available with AC or DC coil voltages and with approvals for use in hazardous areas.
Filter/Regulator
A regulator controls the air pressure used to operate a pneumatically actuated valve. Combined with an air filter and auto-drain to remove any condensation in the line, it also provides protection of downstream pneumatic components and improves system reliability.
Optional Materials
Xylan® Coated Gate
Xylan® is a fluoropolymer-based coating commonly applied to valve components to enhance corrosion resistance, wear resistance, and lubrication properties.
Graphite Packing
Graphite is a carbon-based material widely used in valve seats, packing, gaskets, and seals due to its high-temperature tolerance, chemical inertness, and self-lubricating properties.
