20 Weir Power & Industrial First choice for power and industrial protection Batley Valve BV 6-0810 HYPERSEAL BV22000 Sizes 50 - 1000mm, Class 300 Sizes 50 - 1000mm, Class 150 Sizing & Selection Torques for Sizing Actuators - Inch-Pounds (R - P.T.F.E. Seat) Actuator selection is dependent upon a number of variable factors such as pressure drop across the valve, seat and bearing friction torques, cryogenic temperatures and flowing media. The figures in the following table are based on standard valves and materials working in normal service conditions. A safety factor as recommended by the actuator manufacturer should be applied. Consult Batley Valve for cryogenic torque figures. 316 shafts cannot be used without increasing size Valve Torque Figures (lbf/inches) Valve dia. Spindle dia.
