A Review: Why Kinetrol Actuators Are the Most Reliable 1/4 Turn Pneumatic Actuator on the Market Today

With millions of actuators performing reliably around the world, the Kinetrol vane actuator's are the best choice for valve and damper actuation applications that require long life and ultra-dependable performance. Here's a review as to why:

• Durable epoxy stove enamel exterior finish.
• Long life epoxy or PTFE internal finish.
• Integral vane/shaft casting - only one moving part: Simplest and most reliable mechanism for quarter-turn rotary actuation.
• Manual override square and position indicator.
• Stainless steel expanders ensure long term lipseal / case contact.
• Double opposed, Polyurethane, lip seals for effective sealing and long maintenance free life.
• Space filling/energy absorbent sideplates (polymer or metal).
• Corrosion resistant zinc (non-incendive) or aluminum alloy case.
• Easy stop adjustment at each end of stroke for accurate seating.
• Close couple control modules. Fail-safe spring returns, limit switches, positioners and solenoid valves all close couple to the actuators.
• No cranks or gearing. No power loss or backlash - allows accurate positioning.
• Long maintenance-free life. Up to 4 million operations guaranteed.
• Compact - space saving - efficient. Best torque/size package available, fast operating speeds, best air consumption, proven design.
• Unique serial number for identification and traceability.

Innovative Gate Opening System Driven by Kinetrol Actuators

The customer is a foundry located in the mid-West. Safe access over a conveyor is required over a ramp to allow personnel to come and go as needed. A pneumatic gate and ramp system needed to be designed that would simultaneously open and close two (2) steel gates. The opening and closing would be controlled by a simple hand-switch on the ramp railing.

Two Kinetrol vane actuators are mounted under and on each side of the ramp. Driveshafts connected to the Kinetrol actuators open and close the steel gates. Solenoid valves respond to the hand-switch to pilot the actuators.

The Most Reliable 1/4 Turn Pneumatic Actuator on the Market Today. Period.

With millions of actuators performing reliably around the world, the Kinetrol vane actuator's outstanding cycle life, smooth and precise movement, and environmentally rugged design makes it the best choice for all of your valve actuation needs.

Kinetrol Vane Actuator Outperforms Rack and Pinion on Power Plant Filter-Demineralizer System

Filter-Demineralizer System

An important component of combined cycle power plant design and operation is condensate polishing, commonly referred to as "CP". CP is a process that purifies condensate. High purity condensate maximizes uptime in power plants by maintaining stable condensate chemistry and reducing corrosion transport. Power plants install specialized filter-demineralizer systems which remove both suspended solids and ionic contaminants to maintain optimal condensate  chemistry.

At one midwest power utility company, a valve controlling the flow of water (210 psi and 140 deg. F) that feeds the demineralizer was causing concern. The valve's accompanying rack and pinion actuator was creating a maintenance problem. While this isn't a high cycle application, the system must be 100% reliable, and the old actuator's performance was unreliable. The solution was to install a Kinetrol vane actuator. A new automated valve was installed 6 years ago (2012) and the Kinetrol actuator has operated flawlessly since then.

Cement Hopper Valve Actuator Requires Kinetrol's Accuracy, Dependability and Toughness

Location of the actuator and valve at bottom of hopper.

A midwestern cement plant had a hopper loading system that was being manually controlled. A human operator, using a long pole attached to a valve arm on a hopper, dispensed the flow of cement. The silo is divided internally into 4 sections. Each section has its own 12" butterfly valve which allows product to fall into a single hopper above a weighing scale. At the bottom of the hopper, and above the truck loading spout, the butterfly valve throttles the product into cement trucks.

No only did this approach require a human operator (with associated costs and safety precautions) to be present, the manual system didn't provide the degree of control the company needed. Careful control of the cement into the truck is important because uncontrolled flow, or too rapid a flow, will overwhelm the dust collection system and allow fugitive emissions (dust) to escape to the atmosphere. A serious regulatory and safety issue.

Kinetrol actuators and positioners perform in dirt and dust.

Together, the local Kinetrol Distributor sales rep and customer came up with a new system utilizing a Kinetrol vane actuator and an EL electropneumatic positioner. The new design accurately modulates the cement flow through the 12" valve. This approach gives the customer much closer flow control and eliminates the need to a human operator. It also allows for the terminal to be remotely operated from more than 4 miles away, all with reliable and repeatable results.
