High Temperature Actuator Operated Electric Butterfly Valve , Electric Actuated Butterfly Valve Wide Size Range
How Does Electric Butterfly Valve Work?
Electric butterfly valve is composed of electric actuator and sanitary butterfly valve. So it has the advantages of easy operation and simple structure. It’s also widely used in chemical, pharmaceutical and other industries. And because of the help of the electric actuator, the development of butterfly valve reaches a new level. The mechanism of electric butterfly valve: the electric device drives the valve stem, which makes the butterfly plate rotate 90 degrees to achieve the opening and closing of the valve.
OVERVIEW
The VA16 series butterfly valves can be used for refrigeration and heating systems, as well as for industrial and water treatment systems.
The VA16 series is equipped with standard On-Off or modulating (4~20mA, 1~5V, or 0(2)~10V ) control quarter-turn electric actuator.
FEATURES
• Wide size range (DN 50…DN600)
• For On-Off or Modulating Control
• The handwheel assembly manual adjustment
• Irreversible worm gear.
• Visual mechanical position indicator for accurate visual reference of valve position.
• Anti-condensation heater and 2 aux. limit switches on standard model
• Enclosure IP67
