FAQ: How do you wire devices with metric electrical connections?

Conduit For many years, the use of rigid or liquid-tight conduit was the standard for running wires to field devices, such as safety shut-off valves, pressure switches, and flame safety devices. Rigid conduit is thin walled metal tubing that helps to protect wires from mechanical damage and some environmental factors. Liquid-tight conduit is flexible and Read More

Elektrogas VMRNA Automatic Vent Valve

The Elektrogas VMRNA is a normally-open vent valve for industrial combustion systems. Because the valve is open when de-energized, VMRNA can be thought of as the opposite of a safety shut-off valve (closed when de-energized). How they work A reverse-acting solenoid valve, VMRNA is normally open. That means you must apply power to close the Read More
