Jordon Controls Co., Ltd. was founded in 1955 in the United States. From the to the present, it has been specializing in the production of electric actuators for power plant dampers, especially in harsh conditions (such as: high ambient temperature, limited installation and difficult maintenance, frequent action, etc.). Jordon's products have always been the first choice for the majority of users in the world, due to the manufacturer' nearly fifty years of experience accumulation and advanced design and manufacturing philosophy. In this field, especially in high-frequency modulation applications (the actuator can move up to 200 to 4000 times per hour), its market share in the European and American markets exceeds 70%. The only competitor is Germany's HARTMAN & BRAUN, but the latter's price is more than three times its own. Since entering the Chinese market in 1978 with Shandongitong Power Station, it has now had dozens of power users in China and has never had any problems. From the perspective of the Chinese market, Jordon's products are widely used in the damper, control valve electric head (feedwater, condensate, recirculation, etc.) and quick-opening valve of the flue and wind systeminduced draft fan, coal mill, coal feeder, primary air, secondary air, etc.) in power plants. Jordon's main advantages include high modulation frequency2000-4000 times/hour), integration (motor, servo amplifier and transmission mechanism), permanent lubrication maintenance-free, installation at any angle, positive gear and Scotch yoke transmission mechanism, etc. At present, all well-known domestic brands (such as: ROTORK, SIPOS, AU, etc.) use a separate design, especially the life of the reducer is very short. The use of worm gear transmission mechanism has a large wear, high heat generation, transmission efficiency, short life, and the modulation frequency can only reach up to 1200 times/hour. Moreover, it needs regular lubrication maintenance and cannot be installed any position. Products  ·The Scotch yoke output structure provides an additional 66% torque at both ends of the stroke ·Permanent lubrication installation at any position ·Built-in amplifier (except SM-5140) ·Instant stop and self-locking drive system to prevent reverse driving which can resist the return torque not greater than the rated torque ·AC power (single phase and three phase) or DC power ·Positive and side installation ·Twoyear warranty period
