                                                                                                                YANKE ZPZD31 SERIES POSITIONER

1) Product Introduce

The ZPZD31 series intelligent valve positioner is a microprocessor-based electro-pneumatic valve positioner. It can be controlled

The manufacturing equipment receives DC signals and controls the opening of valves. In addition to this basic function, the ZPZD31 also has the ability to pass

The information capability, automatic configuration program and self-diagnostic function can enhance productivity and the production efficiency of the factory.

2) Main feature

Innovative nonlinear adaptive PID control, with super robust stability and strong anti-interference ability, is widely applicable to different control objects.

※ Quick debugging and setting. The debugging and setting time for control valves with a stroke of 60mm or less (DN200 diameter) is less than 2 minutes. 

Large-diameter valves are based on the air source

The flow can all be quickly adjusted.

※ Traffic configuration control can be selected by default or customized by the user.

※ Position feedback is implemented by software and can change the feedback form to meet the specific requirements of users.

※ HART protocol or FF bus module can be optionally configured;

※ Strong environmental adaptability. The temperature range is available from -40℃ to +70℃ and from -50℃ to +85℃

It is configured for use and can resist shock, vibration and strong electromagnetic interference

It is extremely convenient to debug and use

• Automatic Settings

Its automatic setting software is a fully automatic configuration program. Unlike other brands of smart locators, the ZPZD31 does not require external devices. 

The basic configuration does not require a computer or a dedicated communicator. Just press the setting power button once and the program will 

run automatically to complete the installation and debugging work.

Users can set their own traffic characteristics

Users can set the input/output characteristics of the positioner by themselves, thereby correcting the overall characteristics of the valve to cope with specific production processes.

Self-diagnosis

The self-diagnostic program of ZPZD31 ensures rapid and accurate troubleshooting measures for control valves
