Type series booklet 8505.12/10--10 MR series manual actuators Output torques up to 16 000 Nm MR 25 to 200 : Worm wheel and screwkinematics MR 400 to 1600 : Yoke kinematics MR 25 to 200 MR 400 to 1600 Applications • All sectors of Water, Industry and Energy. General information • The range of MR series manual actuators developed and manufactured by KSB--AMRI covers output torque values up to16000 Nm. • The MR series actuators, equipped with non reversible kinematics in all positions, have been designed for all applications and for the operation of any type ¼ turn valves (centred or double eccentric disc butterfly valves, ball valves,...). • Themounting plate is in accordance with ISO 5211 standard. • Equipped with an interchangeable insert, they can be easily fitted on different valve shaft (square end, flat end, key,…). • These actuators are supplied with a handwheel and a visual pointer. • Factory lubricated (silicone free grease), they do not need any maintenance. • The MR series actuators are equipped, in standard version, with adjustable end stops: -- MR 25 to 200 (±2° ) in the open and closed positions, -- MR 400 to 1600 (±2,5° ) in the closed position. Protection • They are hose and fine dust proof and are protected against accidental immersion effects (protection degree: IP 67). • Variant: suitable construction with protection degree IP 68 (30 water column meters ). External coating • Standard sealed version: Polyurethane paint (colour dark grey RAL 7016, 80 ìm thickness). • Marine version: 2 coat system with colour dark grey epoxy paint finish RAL 7016, 150 ìm average thickness. Working temperature range • From --20°C to +80° C Options • Operation by cardan joint, fountain key, and chain wheel, exchangeable with the handwheel on site, • Electric limit switch box AMTROBOX, • Visual indication by a flag, • Handwheel locking by chain and padlock, • Closing anticlock wise, • Special coating for particular environments, • Input number of turn (only MR 400 to 1600): Adapt construction on request for a number of turn inferior to the input. • Remote control devices.

MR series manual actuators 3 Operation In standard version, MR actuators are designed to ensure clockwise valve closure. On request, anticlockwise arrangement is available. MR 25 to 200: worm wheel and screw non--reversible kinematics in all positions The worm wheel and screw kinematics allows to deliver a constant output torque. Operation is achieved by a device (handwheel, cardan joint, fountain key, chain wheel), linked to the operating screw .. driving in rotation the worm wheel .. integral with the valve shaft. Graph A: constant output torque MR 400 to 1600: yoke non--reversible...
