Industrial Wafer Motorized Butterfly Valve Motor Operated Easy Modulatig

 

Wafer Electric Butterfly Valve , DN50 DN65 DN80 Electrically Operated Butterfly Valve

 

OVERVIEW

 

The electric butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed by rotating 90°, and the operation is simple, and the valve has good fluid control characteristics. The butterfly valve's disc is mounted in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation is 90°, the valve is fully open. When the flange butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics.

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
