This newly engineered valve features all the good characteristics of the s35 RuB mini valve, in particular:
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, superheated steam 1.5
Slurries or liquids bearing abrasive particles 1.5÷2.5
