Dimensions from Susin’s general drawing; letters as on the drawing. * L1, L3, L4, S and D4 are customised to the order, the rest are standard. Rim pull is Susin’s figure at full output torque on the recommended handwheel. Send us the valve and actuator flanges and the torque and we’ll confirm the model.
