In response to the specific needs of domestic industry users, Zhongda Dentsu recently launched a new valve position temperature controller tailored for two-signal-controlled valve position motors. This product is based on the parent company Delta Electronics’ advanced DTB Series Thermostat model – DTB9696RRV. Industry professionals in China are eagerly awaiting this high-performance and cost-effective solution.
In many applications requiring precise fluid control, two types of valves are commonly used: one operates using 4-20 mA current signals, while the other uses DTA or DTB thermostat outputs. The second type, which relies on two output signals to control the motor’s forward and reverse rotation, is especially popular in complex control systems. When the forward signal is active, the motor turns in one direction; when the reverse signal is triggered, it moves the opposite way. If no signal is present, the valve remains at a fixed position.
Zhongda Dentsu has extensive experience in designing temperature control systems for both valve types. By leveraging the technical expertise of Delta Electronics, the company has developed the DTB9696RRV, a valve position temperature controller that integrates all the intelligent features of the DTB series and adds specialized valve position control along with four sets of PID parameters.
Key features of the DTB9696RRV include:
1) A system program specifically designed for valve position control, offering easy parameter setup and high precision, ideal for central air conditioning, freezers, industrial furnaces, and textile equipment.
2) Built-in auto-tuning function for PID parameters, tailored for the valve position system environment.
3) Four pre-set PID parameter sets that can be manually selected or automatically switched based on set temperatures.
4) An external wiring interlock function to prevent simultaneous forward and reverse signals, protecting the motor from damage.
5) Support for valve position feedback signals, customizable via parameters depending on the valve type.
6) Auto-tuning capability that automatically measures key system parameters such as motor running time and feedback signal range without manual input.
7) High-performance output and control methods equivalent to top-tier models in the DTB series.
Since entering the Chinese market, Zhongda Dentsu has made significant progress in inverters, PLCs, thermostats, and servo motors, thanks to the strong technical support from Delta Electronics. The products offer performance comparable to leading international brands, but at a more competitive price. As a result, they have gained a solid user base in industries such as papermaking, textiles, plastics, and construction.
The DTB9696RRV aligns with the DTB series’ capabilities, including analog input/output support and built-in ASCII/RTU communication protocols. This reinforces Delta’s mid-to-high-end positioning in the valve position controller market. In a highly competitive electromechanical sector, product performance and cost-effectiveness are key factors influencing customer decisions. With its robust feature set, the DTB9696RRV is well-positioned to make a strong impact in the market over the next few years.
