Electric Ball Valves
Overview and Selection Guide

About Electric Ball Valves

First of all, let's clear one thing up. The ball valve itself is not electric. When someone says "electric ball valve" they mean a regular ball valve with an electric actuator. Valves built for automating typically have an industry standard (ISO 5211) 4-bolt mounting pad that the actuator mounts to.


Ball Valve Types

Electrically actuated 2-way ball valves are a simple solution for many basic on/off applications. They rotate 90 degrees (quarter-turn) from fully open to fully closed. While they typically operate more slowly than valves with an air-operated pneumatic actuator, it is often the case that electricity is available and compressed air is not. Electric ball valves come in many different materials that are listed below.

Electric Actuator Types

There are many different types of electric actuators available, each with its own advantages and disadvantages. Most work with a geared drive train and a reversing motor with limit switches that stop the motor in each direction. Some offer feedback via electrical signals for lighting indicator lamps or even monitoring the exact position of the valve. Electric actuators also come in a variety of enclosure styles from low-cost and lightweight to heavy duty and explosion proof. Explosion proof does not mean that they will withstand an explosion. It means that it will contain any sparks that would cause an explosion in a hazardous location where there are ignitable fumes or vapors. Electric actuators will have a NEMA (National Electrical Manufacturers Association) rating that describes their suitability for use in different conditions. Be sure to consider and abide by any NEMA regulations for the environment of your installation when selecting an electric valve actuator.
