The RuB s.7641 is the right choice for fluid diversion and is designed with robust maintenance-free components ensuring ease of operation and safety. With a simple 90° turn, you can divert flow from one downstream outlet to the other. It combines traditional manual operation with modern automation. It is also very easy to convert from its sturdy lever handle to ISO 5211 actuator flange assembly. It features low operating torque and a special wear reducing self-compensating valve seat design that meets our 100,000 cycle life test requirement. The valve can be purchased separately, with handle or with a 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 |
