About Electric Eccentric Butterfly Valves
"Electric Eccentric Butterfly Valve" means a regular Eccentric Butterfly valve with an electric actuator. It is a simple solution for many extreme pressure and temperatures applications. They rotate 90 degrees (quarter-turn) from fully open to fully closed. While they typically operate more slowly than valves with a pneumatic actuator, it is often the case that electricity is available and compressed air is not.
The Eccentric Butterfly valve (always know as metal seated butterfly valve) is mainly used in industries that work under extreme pressure and temperatures. The metal seats are designed to make the valve much more versatile and durable, so that they can easily withstand high pressures and temperatures. Common applications that use butterfly valves include: utilities, pulp and paper, oil and gas production, fuel handling systems, marine, petrochemical processing, air conditioning, and refrigeration.
A Eccentric Butterfly operates in a quarter turn style, meaning that rotating the closed disc 90° will fully open the valve, and vice versa. They can also be opened incrementally in order to throttle flow. This can be accomplished manually, but throttling flow is more precise when used in conjunction with an actuator. Actuators can be customized to allow incremental flow, by using modulating boards in the case of electric actuators.
Eccentric Butterfly always refer Double offset or Tripe offset butterfly valve, then WHAT'S DIFFERENT ABOUT ZERO, DOUBLE AND TRIPLE OFFSET BUTTERFLY VALVES? We have a professional answer on the next page
