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.

● Long 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.
