Jiangsu Lan valve electric actuator valve Fig valve actuators rankings

Jiangsu Lan valve General Equipment Co., Ltd. [Main products: stainless steel housing waterproof control box, explosion-proof control box, coal safety control box and manual means. Intelligent controller intelligent multi-turn electric devices accept standard analog current control signal or switch control signal, compared with the position signal of the sensor is, the output shaft of the electric device positioned in the input signal corresponding to the position, complete positioning control, but also according to the chain of control, two-line control signals or events targeted at pre-set position control system, the output shaft torque value unless there is an electric device during operation above the rated torque value or the set torque value Otherwise intelligent controller electric device control system will meet the requirements, send the right commands, triggering a three-phase solid state relay, the motor is turned on three-phase power, electric equipment running. Jiangsu Lan valve General Equipment Co., Ltd. home to assist with installation and commissioning, provision of technical assistance. Three Guarantees products company, service quality, product life-long warranty. Counter decimal counter works. Control of high precision, the reduction of the size of a box in the bevel gear drive pinion pass, then drive working stroke control mechanism. If the motion controller according to the valve opening and closing the position has been adjusted, when the controller with the output shaft to advance the adjusted position (laps), then the cam is rotated by 90 degrees, forcing the micro switch to cut off the motor supply , the motor stops, in order to achieve electrical devices stroke (number of turns) controlled. Jiangsu Lan valve General Equipment Co., Ltd. has always been committed to the "leading technology, quality and efficiency, customer first, the undersigned about compliance" business philosophy. Valve actuators Accessories PT-3D-J-type control module is based on a three-phase AC power source AC380V accept DC4 from the PLC, DCS systems or other operator of ~ 20mA signal to control actuators main technical features Input voltage range: AC340V ~ 420V. Three-phase three-wire, three-phase four-wire system are applicable. ? You can automatically correct three-phase power supply phase sequence and the correct implementation of the valve opening and closing control, users can easily access the actuator electric three-phase power. Input / output signals are through the optical isolation (withstand 2000V surge voltage). · Position feedback signal 4 ~ 20mA load resistance: 50Ω ~ 700Ω, Accuracy: 0.5%; third potentiometer adjustment technology greatly simplifies the adjustment process.
