How To: Automation: Making the Leap to Automation

When considering whether a water processing location is a candidate for automation, it is important to understand why automation is implemented. Automation can reduce labor costs, control devices in remote areas, engage a sequence of operations and increase safety. One of the best ways to add automation to an existing system is to use an actuator instead of a hand-wheel and control the valve with a control cabinet. 

How to Outfit Ball Valves & Actuators

Ball valves are a common choice in water systems because they are inexpensive and have a high temperature and pressure tolerance. The valve works by rotating a metal sphere (the ball) with an empty cylinder (the bore) drilled through the center. By rotating the ball, the bore is either in line with the pipe and allows the media to flow through it, or the bore is perpendicular to the pipe and blocks the flow through it. The valve also may sit in an intermediate position, which offers some flow control. 

Saving Energy With Pneumatics

From the time of its foundation more than 300 years ago, St. Petersburg, Russia, has set standards in architecture and city planning. Now the city is playing a role in the field of drinking water treatment in the largest country in the world. 

Tips for Effective Flow Control

Smooth opening and closing of butterfly valves has a large impact on system performance and long-term reliable operation. It not only extends the life of the valve and actuator, but protects other components and piping in the system. With systems utilizing pneumatic actuation, flow control is achieved by metering the flow of compressed air as it enters or exhausts from the actuator. 

Salinas Control Solution

The Salinas Valley of California, southeast of San Francisco, is referred to as the “salad bowl of the world” due to its abundance of crops such as lettuce, broccoli and peppers. Like many agricultural areas in California, Salinas’ water supply is under stress from high usage, rising population and changing weather patterns. Therefore, every water conservation effort in the valley contributes to the overall health of the vitally important agriculture industry.
