The intelligent variable-frequency electric actuators of Shanghai HuaWu XingLi Fluid Control Co., Ltd. (a joint venture of Shanghai XingLi Fluid Control and HuaWu Co. 300095, high-tech enterprise of Shanghai) are built on the LT series intelligent variable-frequency multi-turn platform: large-torque multi-turn, quarter-turn (>1600Nm) and linear actuators are all formed by combining the LT base unit with a secondary mechanical transmission.

Note: non-self-locking speed sections are not recommended for modulating duty; the LS section accepts 220V single-phase supply; a wide range of supply voltages and frequencies is available. Multi-turn actuators above 1500Nm are assembled from the base unit and an MT secondary stage, reaching nominal torques up to 30,000Nm.

Note: the above is the direct-mount series; the bracket/lever series extends to LTQ-FHA. For quarter-turn duty up to 1600Nm the LTQ series is generally selected; above 1600Nm the LT+WOG combination is used — standard and professional types distinguished by S2/S4 duty — with nominal torques up to 40,000Nm.
Linear actuators combine the LT base unit with LZ linear transmissions; the official thrust range is 3.4~217kN. Output thrust = multi-turn torque ÷ conversion factor; linear speed = output speed × lead of the screw.
