A proportional solenoid valve is an electromagnetic valve designed to respond to a variable power input to regulate the flow of liquid and/or gas proportionately. It is used to control the flow rate ...

Editor’s Note: This is the fifth part in our series of articles on cold rooms. Read Part 1 here: Part 1 —Cold Rooms: An Introduction. As with any refrigeration system, controlling the flow of ...

Determine forces on the valve spool to optimize solenoid size. Designers of spool-type, solenoid-operated hydraulic valves often face the vexing problem of increasing flow while shrinking the size of ...

Directional-control valves are common in pneumatic systems. They control compressed-air flow to cylinders, rotary actuators, grippers, and other mechanisms in packaging, handling, assembly, and ...

I recently wanted to try an automatic faucet idea again. I decided to employ a latching solenoid valve to control the water flow on that enhanced version. Luckily, after some searching, I was able to ...

The new Bendix AD-HFi air dryer features the same design as the AD-HF dryer, which was launched in 2019, but incorporates a solenoid-operated valve that replaces the traditional mechanical governor.

The cruise-control system operates via a mechanical linkage that actuates the throttle according to input from a vacuum motor. Solenoid-operated valves regulate the linkage which, in turn, open or ...

Due to historical engineering decisions made many decades ago, a great many irrigation systems rely on solenoid valves that operate on 24 volts AC. This can be inconvenient if you’re trying to ...
