Operators and Actuators
Gear Box
Bevel gearboxes are used to manually operate large or high-torque linear valves, such as knife gate valves, with reduced input effort. They allow precise valve operation with minimal manual force allowing smooth, controlled operation even under demanding pressure conditions.
Pneumatic Cylinder
Pneumatic cylinders are used to actuate linear valves, such as knife gate valves, in demanding or repetitive process applications. General purpose cylinders provide reliable, consistent operation with minimal maintenance, and are typically used in the water industry and standard industrial processes.
Oversized Cylinder
An oversized cylinder (larger bore) may be utilized in applications where minimum required air pressure cannot be achieved or for applications requiring greater actuation force than normal.
Hydraulic Cylinder
Hydraulic cylinders are typically used to actuate large linear valves, such as knife gate valves, in high-pressure slurry or abrasive applications. Hydraulics provide a high force output from a relatively small size (compared to pneumatic cylinders) offering reliable operation and control in the toughest industrial environments.
Electric Actuator
Electric multi-turn actuators are used to operate knife gate valves in applications requiring precise, automated control or in remote environments where air or hydraulic supplies are unavailable. Electric actuation provides precise positioning, ease of integration with control systems, and lower maintenance.
Options & Accessories
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.
