s.7241L NPT 3-way 4 seats (diverting)


full port 1/2” – 1”
hot forged brass ball valve

The RuB S.7241L 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 of the handle, 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.

The valve can be purchased separately, with handle or with a RuB actuator already mounted.

Torque for actuator sizing in-Ib
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
