Steam service for ball valves

Curves of seat and seal operating conditions for liquid and gas ( not applicable for steam) 

Important: Before considering the torque for the calculation of the ctuator, the fluid which will be used should be taken into account; some substances do not provide internal lubrication to the valve and increase the torque up to 40%. This mainly happens with solvent substances, and therefore the below-mentioned security factor should be taken into account.
