2/2-way ball valve with electric rotary actuator
8804 DN10-65 mm
• Applications for neutral, contaminated or
aggressive mediums
• High flow rate value
• Actuator with adjustable limit switches
• Visual position indicator
• Multi-voltage
The electric ball valve, Type 8804, consists of an electrical rotary actuator Dimensions [mm] (see datasheet for more details)
and a 2/2-way ball valve made of stainless steel full bore. Heat resistor
and torque limiter are standard. The body is made of low inflammable
