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.

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

Cement Hopper Valve Actuator
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.

Power Plant Bearing Cooling Water Temperature Control

A midwest power plant was using a diaphragm control valve to control water temperature for their bearing cooling system. The closed-loop bearing cooling system uses the modulating valve to control water temperature between 50 and 170 degrees F. at 170 PSIG. The diaphragm valve was not able to provide the required signal response for tight control.

The local Kinetrol Distributor specified a high performance butterfly valve (HPBV) with Kinetrol spring return actuator and third-party positioner. The new valve and actuator package provided  reliable and accurate controllability with zero hysteresis. It has operated continually for 3 years without maintenance.
