actuator mounting
full port 1” – 2”
hot forged brass ball valve

More and more automation is required at all levels in our society and the s.64 RuB range is the answer to all needs for reliable actuated ball valve.
It features special seat design to automatically compensate for wear and it has successfully passed 100,000 cycle life tests.
You can purchase the valve alone or with RuB actuator already mounted.

Torque for actuator sizing in-lb
Torque correction factors

Valve torque can vary according to operating frequency, temperature and friction characteristics of the media.
If media has more or less friction than water, multiply torque by the following factors.

Lubricating oils or liquids 0.8
Dry gases, natural gas 1.5
Slurries or liquids bearing abrasive particles 1.5÷2.5
