Janatics KEVA (Knife Edge Valve Actuator) is a robust linear actuator specifically engineered for knife gate valve automation in demanding process applications. Designed to handle abrasive media, slurry, and bulk solids, KEVA actuators deliver high thrust, smooth operation, and long service life, ensuring reliable valve performance even in harsh industrial environments.

Design & Construction

KEVA actuators are built with a focus on strength, durability, and performance under heavy-duty conditions:

• Heavy-duty cylinder construction (MS / FRP options)

• Ductile Iron / Cast end covers for structural integrity

• Precision-machined piston and rod assembly

• High-quality sealing system for leak-free performance

• Corrosion-resistant design suitable for outdoor installations

Operating Principle

The KEVA actuator uses pneumatic pressure to generate linear thrust, enabling precise opening and closing of knife gate valves.

• Direct linear motion ensures efficient force transmission

• Designed to overcome high seating and unseating forces

• Suitable for general automation and process control applications

• Suitable for both on-off and controlled applications

Key Features

• Smooth and consistent linear movement

• Rugged design for abrasive and slurry applications

• Low maintenance with long operational life

• Customizable stroke lengths and mounting configurations

• Suitable for vertical and horizontal installations
