Torque Curves
The working torque of ball valve depends on pressure and ball seat sealing material. For the diagram below, working medium is water, and seal material is POM. Torque is 1.4 times that of POM supposing sealing material is PEEK, 0.8 times for oil, 1.3 times for air, and 1.4 times for granular powder. Actuator torque = 1.2*Torque (1.2: safety factor).
