Azbil Yamatake Smart Valve Positioner AVP307 amplifier for valve positioner
Product Description
Model AVP307, which is a normal current-pneumatic smart valve positioner equipped with a microprocessor, is available for the DC 4 to 20 mA instrumentation now in use and compatible with HART communication and travel transmission output.This normal current-pneumatic positioner provides significantly greater usability than previous models, and covers a wide range of valve specifications with a single model.Furthermore, by using this product to enhance the controllability of the control valve
and monitor the operation of the control valve, maximum cost-effectiveness will be ensured.
Feature
(1) Easy adjustment (only 1 screwdriver can be adjusted) Automatic setting equipment can recognize the installed operator specifications, and set according to different specifications, and automatically adjust appropriate. Simple zero and range adjustment Zero and range adjustment should never interfere with each other. Zero and range points do not change even if other Settings are changed.
(2) A single model is suitable for a variety of specifications. Changing data Settings without changing any parts can be applied to a wide range of valve specifications.
(3) The following diagnostic parameters can be monitored by HART communicator or Valstaff, the maintenance support system for regulating valve.
- Stick-slip coefficient
- Reverse run times
- The product of sliding distances
- Times of full load operation
- The frequency distribution of different opening degrees
- Maximum operating speed
(4) The forced closing characteristics of the valve can arbitrarily set the input signal when the valve is closed.
(5) Convenient maintenance.
As the electrical circuit part and the air circuit part is completely isolated, so the maintenance of the air circuit part is very convenient. Since the automatic/manual switch has been used as standard equipment, it is also very convenient to confirm the working status of the reading door. (However, double-acting mechanisms are not available.)
(6) Openness feedback function
The working state of the regulating valve can be monitored in the control room by using the opening feedback function. (However, because in addition to the input signal line also need to have the opening feedback power loop, so the use of 4-line instrument)
(7) Single or double acting mechanism can be carried.
By installing a double-acting amplifier at the output air pressure connection, it can be mounted on a double-acting mechanism
