Product Description

position Master ABB Digital Valve Positioner For Pressure Control Valve EDP300 Series with chinese brand control valve with stock

The PositionMaster EDP300 is an electronically configurable positioner with communication capabilities, designed for mounting on pneumatic linear or part-turn actuators. It features a compact design, modular construction, and an excellent cost-performance ratio.
Fully automatic determination of the control parameters and adaptation to the actuator allow for considerable time savings as well as optimum control behaviour.

The extended diagnostics feature of the PositionMaster EDP300 provides the user the
opportunity to perform selectable valve performance diagnostics and to schedule Control Valve preventive
maintenance as determined by the results to ensure increased system availability and to minimize
unforeseen cost intensive failures. in this document we provide examples of typical online and offline tests that can be performed by the
EDP300 positioner:
- Partial Stroke Test
- Valve Signature
- Speed over Position Test
- Butterfly Diagnostic
- Drag Indicator
- Valve Step Response

Special features

This test requires the EDP300 Pressure Sensor Module Option.
The Valve Signature, which is displayed via the DTM, is used to
detect the static and sliding friction of the valve. The valve
hysteresis is also displayed, for this purpose the various
positions across the entire valve range are approached in steps.
When the Valve Signature starts, the entire valve operating range
for the ‘open and closed directions’ is covered in an uncontrolled
manner (open loop test). During this process, the pressure
patterns of the diagnostic pressure sensors are recorded using a
configurable number of 10 to 100 positions.
For each step, there is a 4-second delay so that the valve can set
itself after the required position has been reached.
Once the signature test is complete the parameters selected by
the user are loaded from the device and displayed.
Consequently, excessively heavy movement of the valve is
displayed as a greater hysteresis.
Additionally, the position and signal waveform for the optional
Universal Input can also be recorded.
The Valve Signature of a new or refurbished assembly provides
valuable data as the baseline performance for comparison of
valve and actuator condition as part of routine valve
performance verification.
