Modulating DPS kit

Modulating DPS kit

One of the UK biggest offering of Valve Actuation products, offering Electrically and Pneumatically Actuated Valves.

______________________________________________________________________

 
The DPS "Digital Positioner System" kit is pre-installed at the factory when ordered as an option for the J&J actuator or with an electric actuated valve assembly. 

Standard features include:
Option of 0-10V control
Self-calibrating
Provides a proportional output signal
DPS virtually eliminates hunting
Economically priced
The electric actuator with optional DPS kit is controlled by a 4-20mA control signal and provides accurate positioning of the actuator output drive. Any change in the control input signal results in a corresponding and proportional change in the position of the actuator. When used with an electric actuated ball or butterfly valve, the ball or disc can be positioned anywhere between closed and the fully open position (0-100%). Flow is non-linear when used with these type valves.

An internal microprocessor on the DPS circuit board continuously monitors digitally the analog input and output signals and compares them to the physical position via an output shaft feedback system, moving the actuator as required to balance the signals.

Digital control ensures highly sensitive and repeatable control, with all the usual positioner characteristics coming in at under 1% (actuator only - including hysteresis, linearity & precision). Overall accuracy of valve assembly will vary depending on the type of valve used and method of mounting the valve.

The DPS is self calibrating, and on initial start-up or on restoration following a power cut, will go through a short automatic set-up sequence.

In situations where the actuator is used in manual mode (eg: commissioning) and put back into automatic mode with the actuator out of its normal operating quadrant, the DPS will auto-adjust itself back into the correct quadrant, re-set itself, and be ready for use.
