Features
• Moderately price:
Optimized flow rates mean smaller ball valves can be selected. Low torque means
you can combine them with small, less expensive rotary actuators.
• High life expectancy:
Maintenance-free construction, also thanks to low friction stem and polished ball
made of chrome-plated DZR brass.
• Simple mounting:
The brackets, premounted on the actuators, means you can mount them on the
ball valves without tools.
