How To Install and Remove a Kinetrol Actuator Spring Unit

This video demonstrates how to install and removed a spring unit for a Kinetrol vane actuator. Spring units are available for either clockwise or counter clockwise spring action. They are mounted, as standard, between the actuator and what it drives. With spring units alone, direction is determined by looking at the unit from the end which interfaces with the actuator.

Permanent mold casting (PMC) is a metal casting process that employs reusable molds, usually made from metal. Common permanent mold casting casting metals are aluminum, magnesium, and copper alloys. Other materials include tin, zinc, and lead alloys and iron and steel are also cast in graphite molds. The permanent mold process has a number of advantages over other casting techniques. Benefits of permanent mold casting are:

• No waste from the mold
• Reusable mold
• Good surface finish
• Good dimensional accuracy
• High production rates
• Higher conductivity levels

Kinetrol actuator replacement. The actuator mounts directly to equipment,
connected directly to the shaft eliminating the need for rods and yokes.

A foundry in the North Central USA was using a hydraulic cylinder to continuously position an armature on each side of a piece of foundry equipment. The movement of the cylinder and associated hardware was limited to 60 degrees of rotation for the application. The mounting style and location of the hydraulic cylinder made it very difficult to access and adjust. To make things worse, the cylinder design and it's associated rods and yokes compounded the need for adjustment due to wear.

The local Kinetrol Distributor was called in and immediately saw the opportunity to replace the hydraulic cylinder, rods, and scotch-yokes with a Kinetrol actuator and simple mounting.

The Kinetrol actuators have been working for several years now, moving continuously without problem and eliminating the need for frequent adjustments.
