Torque can vary depending on temperature and type of fluid; a safety factor of 1.4 must be applied. Torque can drop on high frequency of operations. The actuator/valve sizing, indicated on the following pages, are based for valves to be used with liquids or gaseous fluids, clean, and for medium temperatures. For further information, or different uses please contact our sales department.
Plan for "L" port
N.B.: “A” must be the rest position of the ball with SR FAIL CLOSE actuator. “B” must be the rest position of the ball with SR FAIL OPEN actuator.
