Recently, the “Industrialization of Intelligent Valve Positioners†project supported by the National Development and Reform Commission has been completed and accepted. The project was undertaken by Hunan Hengyang Radio General Factory and formed a batch production capacity of intelligent valve positioner.
From Hunan Hengyang Radio Factory (now Hengyang North Optoelectronics Information Technology Co., Ltd., the product has the following main features and functions:
★ modular modular structure, fewer moving parts, extremely low failure rate.
★ ultra-low power microprocessors.
★ I/P conversion module that resists strong vibration and anti-magnetic fields.
★ It can be directly applied to air-opening and air-closing valves of linear actuators and quarter-turn actuators.
★ It has the function of automatic recognition of the positive and negative effects of the implementing agency.
★ Simple and convenient operation, one-click setting method.
★ Split control of the input signal: 4-12mA, 12-20mA split.
★ With valve position feedback function.
★ With "HART" communication function.
★ can be arbitrarily change the actuator flow characteristics, such as: linear, equal percentage, quick opening, custom curves.
★ Double-acting function can control the spring-free cylinder actuator.
