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.
Positioner
Positioners are used in conjunction with pneumatically actuated valves to allow variable opening and closing for flow control based on process conditions. Different types of positioners are available and including smart positioners with digital programming. Explosion proof versions are also available, as well as stainless steel enclosures for corrosive environments.
Optional Materials
Chrome Coated Gate
Chroming (hard chrome or electroplated chromium) is a metallic surface treatment applied to valve components to enhance wear resistance, reduce friction, and improve corrosion protection.
Xylan® Coated Gate
Xylan® is a fluoropolymer-based coating commonly applied to valve components to enhance corrosion resistance, wear resistance, and lubrication properties.
